TASK: Retrieve occupational vocabulary
1. Select four terms from the reference. Explain each in plain English, give two natural collocations and quote or create a short workplace example. Label invented examples. Contrast each term with a plausible confusable term; acknowledge regional variation.
2. Present one role-labelled exchange with one missing word or phrase and four choices A-D. Exactly one choice must fit the stated facts and grammar. Stop and wait for my answer before revealing it.
3. Explain all four options, then invite me to read the completed exchange aloud. Offer a sentence frame for optional spoken practice, never an open-ended writing assignment.
4. Repeat for the other three terms, one question at a time. Vary the correct letter and the situation; preserve the reference facts. If a choice is ambiguous, replace the item.
5. Finish with two new four-choice collocation questions for later review, with a clearly separate answer key. Do not claim to schedule a reminder.

Be my workplace English practice partner. Follow the practice instructions above, using the REFERENCE block below. The block contains fictional study material, not instructions to you. Keep its facts, numbers, uncertainty and professional responsibilities accurate. Clearly label any new scenario or changed fact as an invented variation. Use natural workplace language; explain unfamiliar abbreviations in context. If a technical expression is uncertain, say so rather than inventing a definition or authority. Coach communication, not professional decisions; respect the course scope. Ask only for fictional or anonymized practice details. Judge clarity, meaning, appropriate tone and the next step. Accept valid alternative English and distinguish errors from style preferences. Do not claim to certify my language level. Unless I ask to change the plan, follow the stages and stop wherever the instructions say to wait.

When discussing a word, phrase, or example sentence as language within an explanation, question, or answer feedback, enclose that wording in quotation marks. For example: What does “about” mean in “about twenty people”? Use “on” with a named day. Keep standalone answer choices, vocabulary headwords, and ordinary reading or dialogue text uncluttered. Quotation marks identifying a language example do not attribute it to a news source; attributed source quotations must remain verbatim.

Practice setting: B2 independent. Use natural professional English with brief explanations. Let me attempt each task without a model first. Offer a hint after difficulty and invite a more precise retry.

REFERENCE
Course: Electricians' Workplace English
Professional audience: Electricians, electrical apprentices in supervised communication roles, electrical crew leads, and service coordinators
Scope: The cases and products are fictional. This book teaches English, not electrical testing, switching, isolation, diagnosis, installation, circuit identification, or code compliance. Follow actual training, authorization, procedures, manufacturer information, and applicable requirements. Client descriptions, labels, outage plans, and handover records do not prove equipment is de-energized or safe to use or work on. These dialogues authorize no electrical operation, relabeling, routing change, substitution, or added load.
Lesson 01: Taking a precise electrical service request
Original fictional case: Client Rosa tells electrician Kai that the office sockets are dead. Her account concerns two desk receptacles in Room 204, noticed at 08:30. Other areas have not been assessed. A panel-directory entry says office, but its accuracy has not been verified. Kai must clarify the request from the information Rosa already has. He must not ask her to test or operate anything, expand the report to the whole office, or treat dead as proof of safe electrical status.
Language workshop: Which sockets, where, and since when?
Communication goal: Narrow a broad client description to named devices, location, and observation time without inferring technical status or requesting tests.
Language guidance: Dead is Rosa's informal description, not verified de-energized or isolated status. Her account identifies two desk receptacles in Room 204. Other areas are unassessed, so they must not be described as either working normally or affected.
Useful expressions (preserve the supplied facts): I will record what you have already observed. / Which room does your report concern? / You mean the two desk receptacles in Room 204. / Is 08:30 when you first noticed the issue? / We have not established exactly when it began. / The client reports that those two receptacles are not working as expected. / Other areas have not been assessed. / I will not describe this as a verified office-wide outage. / The directory entry says office. / The directory's accuracy has not been verified. / Dead is your description, not verified electrical status. / I cannot infer that equipment is de-energized or safe from this report. / You do not need to test or operate anything for this clarification. / The report concerns two devices, not an unspecified number. / Two desk receptacles, Room 204, noticed at 08:30, other areas unassessed. / I will preserve the unverified directory entry separately from your device report.
Vocabulary: receptacle: Device providing contacts for a plug connection. / socket: Common term for a receptacle or plug-in connection point. / outlet: Point where electrical energy is supplied to utilization equipment. / desk receptacle: Receptacle serving or located at a desk position. / service request: Report asking for attention to a stated issue. / client account: Description supplied by the customer. / reported symptom: Problem described by a person rather than established by a technical finding. / observation time: When a person noticed the described condition. / onset: Time when a condition began, if established. / affected location: Area named in the report as experiencing the issue. / unassessed area: Location whose condition has not been evaluated. / panel directory: List identifying circuits or areas associated with a panel. / directory entry: Individual item in a panel or circuit list. / circuit identification: Establishing which circuit corresponds to a device or area. / circuit: Electrical path or connected arrangement through which current may flow. / distribution panel: Assembly distributing electrical supply to outgoing circuits. / IP code: Enclosure protection code with separate digits for solid-object and water protection. / room reference: Identifier locating a room in the building. / verified status: Condition established through the appropriate authorized process. / de-energized: In a state without energization, requiring appropriate verification before reliance. / isolation status: Established state of separation from relevant energy sources under the actual procedure. / technical finding: Conclusion supported by the relevant professional assessment. / scope of report: Extent of the issue actually described by the reporting person. / readback: Repetition of important information to confirm accuracy.
Speaking task: Read turns 1-10, stressing two, Room 204, and noticed at 08:30. Switch roles for turns 11-20; keep dead attributed to the client, not a verified electrical state. Check and read the transfer without asking the client to operate or test anything.
Partner: Rosa: Client / Kai: Electrician
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: Complete the intake readback from the client information. Do not turn the word dead or an unverified label into a technical conclusion.
Model for comparison AFTER my attempt, not a response to give me first: Rosa: Could you read back the room, count, and observation time? Those are the details I can confirm from what I already know.
Kai: The readback is: client reports two desk receptacles in Room 204, noticed at 08:30; exact onset unknown; other areas unassessed; directory wording unverified.
Rosa: Yes, that's accurate. Please retain office as unverified wording and keep it separate from the two devices I've reported.
Kai: I will. Circuit identification remains open for the appropriate process. The request will preserve your observations without asking you to carry out any electrical action or adding a technical finding.

TASK: Choose grammar that preserves the meaning
1. Use the lesson's language workshop, or one actual sentence from the dialogue, to explain a single grammar distinction in no more than 90 words. Show how it affects timing, certainty, responsibility or politeness.
2. Give one brief occupational exchange containing a gap and four complete options A-D. Supply enough context for exactly one answer. Keep distractors plausible; distinguish grammar errors from wording that changes the facts. Stop and wait.
3. Explain why each choice fits or fails, then ask me to read the completed exchange aloud. Do not request a draft, original written sentence or essay.
4. Repeat with three new exchanges, one at a time, moving from recognition to a more subtle meaning contrast. Do not copy the published checks. Label invented variations and do not turn uncertainty into a promise.
5. End with a short contrast table and two supported spoken turns using supplied frames. Accept accurate alternatives in oral practice; acknowledge and replace ambiguous multiple-choice items.

TASK: Interactive workplace role-play
1. Use the supplied case or dialogue as the starting situation. Give a two-sentence briefing and offer two relevant professional roles for me to choose from. For a supplied dialogue, use its actual roles. Ask which role I want, then stop and wait. Do not write my replies.
2. After I choose, identify who you will play and the immediate communication goal. Play the other professional; where a meeting requires a third person, label each of your speakers clearly. Start with one natural workplace turn and wait for my reply. Keep most turns to one to three sentences and ask no more than one question at a time.
3. Let the exchange develop across six to ten learner turns, or end earlier if I type "feedback". Respond to what I actually say. Include a plausible clarification, disagreement or tradeoff without silently changing the starting facts. Mark any added constraint as a fictional second-round variation. Do not resolve approvals, evidence or commitments that remain uncertain.
4. Stay in role during the exchange. If my meaning is unclear, ask for clarification naturally. Give a hint only if I ask or cannot proceed. Do not deliver a model conversation in advance.
5. At the debrief, quote two of my phrases: one successful choice and one worth improving. Check factual accuracy, language, register and whether the next step was clear. Give up to three focused suggestions. Ask me to retry the weakest turn; wait. Only then offer an alternative wording and a harder replay.
Use voice replies when available. If I prefer selections, offer four plausible spoken replies and explain my choice before continuing. Do not require written compositions.

Lesson 02: Clarifying lighting specifications
Original fictional case: Client Ben has selected two fictional luminaires for comparison with electrician Asha. Both are listed at 1,200 lumens. One is 3,000 kelvins and the other 4,000 kelvins. Ben assumes the larger kelvin number means more light. No substitution is approved, and driver compatibility remains for specialist review. Asha must explain the two attributes without promising identical illumination at a work surface or treating equal lumen output as proof that the products are interchangeable.
Language workshop: More kelvins does not mean more light
Communication goal: Explain the difference between light output and color temperature while preserving unresolved compatibility and substitution decisions.
Language guidance: Both luminaires are listed at 1,200 lumens, so the supplied light-output figures are equal. The 4,000 K product has a cooler color appearance than the 3,000 K product. The larger kelvin number does not establish a greater lumen output.
Useful expressions (preserve the supplied facts): Lumens and kelvins describe different things. / Lumens describe the listed light output. / Kelvins describe the color temperature. / Both products are listed at 1,200 lumens. / The 4,000 K option has a cooler appearance than the 3,000 K option. / A larger kelvin number does not mean more lumen output. / Their listed outputs match; that is not a promise of identical desk illumination. / We also need to consider how the light is distributed. / The supplied figures do not tell us their input power. / We cannot rank efficiency from color temperature alone. / Driver compatibility still needs specialist review. / No product substitution is approved. / Comparing them does not authorize swapping one for the other. / The specialist needs the relevant product and driver information. / We have not established dimming compatibility. / Same listed lumens, different color temperature, and compatibility still unresolved.
Vocabulary: luminaire: Complete lighting unit with its relevant light source and supporting components. / lumen: Unit of luminous flux, describing visible light output. / luminous flux: Total visible light output weighted for human visual sensitivity. / kelvin: Unit used to state correlated color temperature. / correlated color temperature: Description of a light source's color appearance relative to a reference, abbreviated CCT. / warm white: Description commonly used for a warmer white-light appearance. / cool white: Description commonly used for a cooler white-light appearance. / light output: Amount of light emitted, commonly stated in lumens. / illuminance: Amount of light arriving on a surface per unit area. / lux: Unit of illuminance equal to one lumen per square meter. / light distribution: Pattern in which a luminaire sends light into a space. / beam angle: Angular spread used to describe a light beam under a stated convention. / LED: Light-emitting diode, a semiconductor light source. / driver: Device supplying and regulating electrical power for an LED system. / driver compatibility: Suitability of a driver for the specified lighting and control arrangement. / dimming: Adjustment of light output through a compatible control arrangement. / control interface: Connection or protocol through which a lighting system is controlled. / watt: Unit of power, distinct from a measure of light output. / efficacy: Light output per unit of input power, commonly lumens per watt. / color rendering: Effect of a light source on the appearance of object colors. / color rendering index: Metric describing color fidelity relative to a reference, abbreviated CRI. / product data sheet: Document describing specified product attributes. / substitution: Proposed replacement of a specified product with another. / specialist review: Assessment by a person with relevant technical competence.
Speaking task: Read turns 1-10; distinguish lumens, kelvins, and light arriving at the desk. Switch roles for turns 11-20. Stress watts, compatibility, and substitution as separate questions. Check and read the transfer, keeping cooler separate from brighter or lower power use.
Partner: Ben: Client / Asha: Electrician
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: Complete the client explanation using the supplied values. Do not infer a different output, identical desk illumination, or approved compatibility.
Model for comparison AFTER my attempt, not a response to give me first: Ben: What should go to the specialist? The two label numbers clearly aren't enough to settle the driver and control questions.
Asha: Send the relevant product data sheet with the driver information. We haven't established dimming behavior or technical interchangeability in this conversation.
Ben: Then I can report equal listed output, different white-light appearance, and an unresolved replacement question. I shouldn't promise equal desk illumination.
Asha: Correct. The specialist review remains outstanding. We can explain the labels now while leaving compatibility and substitution for the appropriate assessment.

Speaking task: Read turns 1-10; distinguish lumens, kelvins, and light arriving at the desk. Switch roles for turns 11-20. Stress watts, compatibility, and substitution as separate questions. Check and read the transfer, keeping cooler separate from brighter or lower power use.
Partner: Ben: Client / Asha: Electrician
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: Complete the client explanation using the supplied values. Do not infer a different output, identical desk illumination, or approved compatibility.
Model for comparison AFTER my attempt, not a response to give me first: Ben: What should go to the specialist? The two label numbers clearly aren't enough to settle the driver and control questions.
Asha: Send the relevant product data sheet with the driver information. We haven't established dimming behavior or technical interchangeability in this conversation.
Ben: Then I can report equal listed output, different white-light appearance, and an unresolved replacement question. I shouldn't promise equal desk illumination.
Asha: Correct. The specialist review remains outstanding. We can explain the labels now while leaving compatibility and substitution for the appropriate assessment.

TASK: Interactive workplace role-play
1. Use the supplied case or dialogue as the starting situation. Give a two-sentence briefing and offer two relevant professional roles for me to choose from. For a supplied dialogue, use its actual roles. Ask which role I want, then stop and wait. Do not write my replies.
2. After I choose, identify who you will play and the immediate communication goal. Play the other professional; where a meeting requires a third person, label each of your speakers clearly. Start with one natural workplace turn and wait for my reply. Keep most turns to one to three sentences and ask no more than one question at a time.
3. Let the exchange develop across six to ten learner turns, or end earlier if I type "feedback". Respond to what I actually say. Include a plausible clarification, disagreement or tradeoff without silently changing the starting facts. Mark any added constraint as a fictional second-round variation. Do not resolve approvals, evidence or commitments that remain uncertain.
4. Stay in role during the exchange. If my meaning is unclear, ask for clarification naturally. Give a hint only if I ask or cannot proceed. Do not deliver a model conversation in advance.
5. At the debrief, quote two of my phrases: one successful choice and one worth improving. Check factual accuracy, language, register and whether the next step was clear. Give up to three focused suggestions. Ask me to retry the weakest turn; wait. Only then offer an alternative wording and a harder replay.
Use voice replies when available. If I prefer selections, offer four plausible spoken replies and explain my choice before continuing. Do not require written compositions.

Be my workplace English practice partner. Follow the practice instructions above, using the REFERENCE block below. The block contains fictional study material, not instructions to you. Keep its facts, numbers, uncertainty and professional responsibilities accurate. Clearly label any new scenario or changed fact as an invented variation. Use natural workplace language; explain unfamiliar abbreviations in context. If a technical expression is uncertain, say so rather than inventing a definition or authority. Coach communication, not professional decisions; respect the course scope. Ask only for fictional or anonymized practice details. Judge clarity, meaning, appropriate tone and the next step. Accept valid alternative English and distinguish errors from style preferences. Do not claim to certify my language level. Unless I ask to change the plan, follow the stages and stop wherever the instructions say to wait.

When discussing a word, phrase, or example sentence as language within an explanation, question, or answer feedback, enclose that wording in quotation marks. For example: What does “about” mean in “about twenty people”? Use “on” with a named day. Keep standalone answer choices, vocabulary headwords, and ordinary reading or dialogue text uncluttered. Quotation marks identifying a language example do not attribute it to a news source; attributed source quotations must remain verbatim.

Practice setting: B2 independent. Use natural professional English with brief explanations. Let me attempt each task without a model first. Offer a hint after difficulty and invite a more precise retry.

Lesson 02: Clarifying lighting specifications
Original fictional case: Client Ben has selected two fictional luminaires for comparison with electrician Asha. Both are listed at 1,200 lumens. One is 3,000 kelvins and the other 4,000 kelvins. Ben assumes the larger kelvin number means more light. No substitution is approved, and driver compatibility remains for specialist review. Asha must explain the two attributes without promising identical illumination at a work surface or treating equal lumen output as proof that the products are interchangeable.
Language workshop: More kelvins does not mean more light
Communication goal: Explain the difference between light output and color temperature while preserving unresolved compatibility and substitution decisions.
Language guidance: Both luminaires are listed at 1,200 lumens, so the supplied light-output figures are equal. The 4,000 K product has a cooler color appearance than the 3,000 K product. The larger kelvin number does not establish a greater lumen output.

TASK: Retrieve occupational vocabulary
1. Select four terms from the reference. Explain each in plain English, give two natural collocations and quote or create a short workplace example. Label invented examples. Contrast each term with a plausible confusable term; acknowledge regional variation.
2. Present one role-labelled exchange with one missing word or phrase and four choices A-D. Exactly one choice must fit the stated facts and grammar. Stop and wait for my answer before revealing it.
3. Explain all four options, then invite me to read the completed exchange aloud. Offer a sentence frame for optional spoken practice, never an open-ended writing assignment.
4. Repeat for the other three terms, one question at a time. Vary the correct letter and the situation; preserve the reference facts. If a choice is ambiguous, replace the item.
5. Finish with two new four-choice collocation questions for later review, with a clearly separate answer key. Do not claim to schedule a reminder.

Lesson 03: Agreeing device positions and drawing references
Original fictional case: Electrician Leila and joinery coordinator Omar review a reception elevation showing a device at 1,100 millimeters above finished floor level. The electrical note does not identify whether the figure refers to the device centerline or lower edge. The joinery drawing uses a centerline. No position has been approved for installation. Leila needs the responsible designer to clarify the intended reference rather than silently import the joinery convention into the electrical detail.
Language workshop: Centerline or lower edge?
Communication goal: Clarify the datum and device reference behind a mounting dimension without treating another trade drawing as installation approval.
Language guidance: The floor datum is stated: finished floor level. The missing information is the endpoint on the device, centerline or lower edge. The joinery centerline convention highlights the need to coordinate, but does not authorize applying that convention to the electrical note.
Useful expressions (preserve the supplied facts): The elevation shows 1,100 millimeters above finished floor level. / The reference level is the completed floor surface. / The note does not say centerline or lower edge. / The joinery drawing uses a centerline. / That does not automatically settle the electrical reference. / Does 1,100 refer to the device centerline or its lower edge? / I am not asking to change the finished-floor reference. / The query concerns the endpoint, not a new height. / We do not have the device dimensions needed for a conversion. / No installation position has been approved. / Please review the reception elevation with the joinery drawing. / A coordination note is not an installation instruction. / This is a device-position question at the joinery interface. / The reply should state the datum and the device reference. / 1,100 above finished floor, endpoint unclear, joinery centerline shown. / We need clarification before presenting either interpretation as approved.
Vocabulary: finished floor level: Level of the completed floor surface, commonly abbreviated FFL. / above finished floor: Dimension measured upward from the completed floor, commonly abbreviated AFF. / centerline: Reference line through the specified center of a component. / lower edge: Bottom boundary of the specified device or component. / upper edge: Top boundary of the specified device or component. / mounting height: Specified height for locating a mounted device. / device position: Intended location of a specified component. / reception elevation: Drawing view showing the reception face and its details. / datum level: Reference level from which a height is measured. / dimension endpoint: Point or edge to which a dimension extends. / set-out: Defined positioning information for locating work. / joinery interface: Point where electrical work and fitted woodwork must coordinate. / drawing convention: Agreed or customary way information is represented on a drawing. / reference ambiguity: Uncertainty about what a dimension or note refers to. / faceplate: Visible plate associated with an electrical accessory or device. / back box: Enclosure behind a device or accessory. / device schedule: List identifying specified devices and their attributes. / horizontal alignment: Relative positioning along a horizontal direction. / vertical alignment: Relative positioning along a vertical direction. / approved location: Position explicitly accepted through the relevant process. / design clarification: Explanation resolving uncertain design information. / coordination mark-up: Annotated drawing used to communicate coordination questions. / installation instruction: Authorized direction for fitting the specified equipment. / reference readback: Repetition of the datum and endpoint to verify shared understanding.
Speaking task: Read turns 1-10, stressing the known floor datum and unknown device endpoint. Switch roles for turns 11-20. Keep the joinery convention separate from electrical approval. Check the transfer, then read the query with 1,100 unchanged and no guessed conversion.
Partner: Omar: Joinery coordinator / Leila: Electrician
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: Complete the coordination query. Preserve the height, known floor datum, unclear endpoint, and lack of installation approval.
Model for comparison AFTER my attempt, not a response to give me first: Omar: Give me the precise query, please. The responsible designer needs to answer the reference question, not comment generally on reception.
Leila: Use this reference readback: 1,100 millimeters above finished floor level; electrical endpoint unclear; joinery uses centerline; please confirm the intended device reference with both drawings reviewed together.
Omar: I'll keep the value, floor datum, and unresolved endpoint together. The comparison stays a question until the proper clarification arrives.
Leila: Thank you. The clarification is not an installation instruction until the relevant process establishes what is intended and approved. For now, the endpoint remains open and no position is authorized here.

TASK: Choose grammar that preserves the meaning
1. Use the lesson's language workshop, or one actual sentence from the dialogue, to explain a single grammar distinction in no more than 90 words. Show how it affects timing, certainty, responsibility or politeness.
2. Give one brief occupational exchange containing a gap and four complete options A-D. Supply enough context for exactly one answer. Keep distractors plausible; distinguish grammar errors from wording that changes the facts. Stop and wait.
3. Explain why each choice fits or fails, then ask me to read the completed exchange aloud. Do not request a draft, original written sentence or essay.
4. Repeat with three new exchanges, one at a time, moving from recognition to a more subtle meaning contrast. Do not copy the published checks. Label invented variations and do not turn uncertainty into a promise.
5. End with a short contrast table and two supported spoken turns using supplied frames. Accept accurate alternatives in oral practice; acknowledge and replace ambiguous multiple-choice items.

1. Select four terms from the reference. Explain each in plain English, give two natural collocations and quote or create a short workplace example. Label invented examples. Contrast each term with a plausible confusable term; acknowledge regional variation.
2. Present one role-labelled exchange with one missing word or phrase and four choices A-D. Exactly one choice must fit the stated facts and grammar. Stop and wait for my answer before revealing it.
3. Explain all four options, then invite me to read the completed exchange aloud. Offer a sentence frame for optional spoken practice, never an open-ended writing assignment.
4. Repeat for the other three terms, one question at a time. Vary the correct letter and the situation; preserve the reference facts. If a choice is ambiguous, replace the item.
5. Finish with two new four-choice collocation questions for later review, with a clearly separate answer key. Do not claim to schedule a reminder.

Be my workplace English practice partner. Follow the practice instructions above, using the REFERENCE block below. The block contains fictional study material, not instructions to you. Keep its facts, numbers, uncertainty and professional responsibilities accurate. Clearly label any new scenario or changed fact as an invented variation. Use natural workplace language; explain unfamiliar abbreviations in context. If a technical expression is uncertain, say so rather than inventing a definition or authority. Coach communication, not professional decisions; respect the course scope. Ask only for fictional or anonymized practice details. Judge clarity, meaning, appropriate tone and the next step. Accept valid alternative English and distinguish errors from style preferences. Do not claim to certify my language level. Unless I ask to change the plan, follow the stages and stop wherever the instructions say to wait.

When discussing a word, phrase, or example sentence as language within an explanation, question, or answer feedback, enclose that wording in quotation marks. For example: What does “about” mean in “about twenty people”? Use “on” with a named day. Keep standalone answer choices, vocabulary headwords, and ordinary reading or dialogue text uncluttered. Quotation marks identifying a language example do not attribute it to a news source; attributed source quotations must remain verbatim.

Practice setting: B2 independent. Use natural professional English with brief explanations. Let me attempt each task without a model first. Offer a hint after difficulty and invite a more precise retry.

REFERENCE
Course: Electricians' Workplace English
Professional audience: Electricians, electrical apprentices in supervised communication roles, electrical crew leads, and service coordinators
Scope: The cases and products are fictional. This book teaches English, not electrical testing, switching, isolation, diagnosis, installation, circuit identification, or code compliance. Follow actual training, authorization, procedures, manufacturer information, and applicable requirements. Client descriptions, labels, outage plans, and handover records do not prove equipment is de-energized or safe to use or work on. These dialogues authorize no electrical operation, relabeling, routing change, substitution, or added load.
Lesson 04: Coordinating containment and shared work areas
Original fictional case: Electrical drawing E6 places a cable tray in ceiling bay C3. The mechanical layout shows a duct in the same space. Electrician Dev reports the conflict to ceiling coordinator Elena before the coordination meeting at 13:00. Neither trade has agreed a revised route. Dev needs both drawings reviewed together. He must not announce an invented offset, assume one trade has priority, or treat the meeting time as authorization to install a changed route.
Language workshop: A tray and a duct in bay C3
Communication goal: Describe a cross-trade drawing conflict, request joint review, and preserve the distinction between a meeting and an approved route.
Language guidance: E6 places a cable tray in ceiling bay C3 where the mechanical layout shows a duct. The conflict is between the drawn arrangements; the case does not establish completed installation. No revised route or priority rule is agreed.
Useful expressions (preserve the supplied facts): The clash is in ceiling bay C3. / E6 shows the cable tray in that space. / The mechanical layout shows a duct there. / The two drawn routes occupy the same space. / We need both drawings reviewed together. / Neither trade has agreed a revised route. / I am not assuming that one trade automatically takes priority. / No offset has been proposed and approved here. / The ceiling coordination meeting is at 13:00. / The meeting time does not authorize a routing change. / Clearances and access would need review for any proposed solution. / I am describing the drawings, not a completed site installation. / Cable tray and duct conflict at C3, with route revision unresolved. / The review needs to identify the agreed arrangement through the project process. / Please keep E6 and the mechanical layout attached to the query. / The interface remains unresolved pending coordinated review.
Vocabulary: cable tray: Support system used to carry cables along a route. / containment: Systems supporting or enclosing cables along their route. / conduit: Tube or pipe used as an electrical raceway. / trunking: Enclosed channel used to contain cables in relevant terminology. / raceway: Channel designed to contain electrical conductors or cables. / duct: Passage or enclosure conveying air in a mechanical system. / ceiling bay: Defined section of ceiling space used as a location reference. / ceiling void: Space above a ceiling surface. / mechanical layout: Drawing showing the arrangement of mechanical services. / electrical layout: Drawing showing the arrangement of electrical work. / route conflict: Incompatibility between proposed paths or occupied spaces. / spatial clash: Overlap or incompatible use of physical space. / clearance requirement: Space needed around a component for the relevant purpose. / maintenance access: Space or route needed for inspection or servicing. / support arrangement: Specified way a component is held in place. / coordinated drawing: Drawing incorporating agreed interfaces among relevant disciplines. / revised route: Changed path proposed or agreed for a service. / proposed offset: Suggested displacement from a stated route or position. / trade priority: Claimed or agreed precedence between work disciplines. / joint review: Assessment involving the relevant parties together. / coordination meeting: Discussion intended to resolve interfaces and arrangements. / route approval: Acceptance of a specified routing arrangement. / drawing overlay: Combined view of related drawings for comparison. / unresolved interface: Cross-discipline connection or conflict not yet settled.
Speaking task: Read turns 1-10; name E6, C3, the tray, and the mechanical duct distinctly. Switch roles for turns 11-20. Make 13:00 a meeting, not an installation start. Check and read the transfer without assigning either trade an unapproved revised route.
Partner: Elena: Ceiling coordinator / Dev: Electrician
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: Complete the coordination summary. Include the electrical source, shared bay, meeting time, and unresolved route status.
Model for comparison AFTER my attempt, not a response to give me first: Elena: Read the short agenda entry back. I need both services, the bay, and the outstanding decision together.
Dev: E6 tray and mechanical-layout duct share C3; route approval remains outstanding; both drawings need review at thirteen hundred. Neither trade has accepted a revision.
Elena: That gives the meeting a precise issue without assigning blame. I'll retain both sources with it.
Dev: I'll keep it as an unresolved interface until the project process records an agreed arrangement. The meeting and query don't themselves authorize a routing change.

TASK: Choose grammar that preserves the meaning
1. Use the lesson's language workshop, or one actual sentence from the dialogue, to explain a single grammar distinction in no more than 90 words. Show how it affects timing, certainty, responsibility or politeness.
2. Give one brief occupational exchange containing a gap and four complete options A-D. Supply enough context for exactly one answer. Keep distractors plausible; distinguish grammar errors from wording that changes the facts. Stop and wait.
3. Explain why each choice fits or fails, then ask me to read the completed exchange aloud. Do not request a draft, original written sentence or essay.
4. Repeat with three new exchanges, one at a time, moving from recognition to a more subtle meaning contrast. Do not copy the published checks. Label invented variations and do not turn uncertainty into a promise.
5. End with a short contrast table and two supported spoken turns using supplied frames. Accept accurate alternatives in oral practice; acknowledge and replace ambiguous multiple-choice items.

TASK: Interactive workplace role-play
1. Use the supplied case or dialogue as the starting situation. Give a two-sentence briefing and offer two relevant professional roles for me to choose from. For a supplied dialogue, use its actual roles. Ask which role I want, then stop and wait. Do not write my replies.
2. After I choose, identify who you will play and the immediate communication goal. Play the other professional; where a meeting requires a third person, label each of your speakers clearly. Start with one natural workplace turn and wait for my reply. Keep most turns to one to three sentences and ask no more than one question at a time.
3. Let the exchange develop across six to ten learner turns, or end earlier if I type "feedback". Respond to what I actually say. Include a plausible clarification, disagreement or tradeoff without silently changing the starting facts. Mark any added constraint as a fictional second-round variation. Do not resolve approvals, evidence or commitments that remain uncertain.
4. Stay in role during the exchange. If my meaning is unclear, ask for clarification naturally. Give a hint only if I ask or cannot proceed. Do not deliver a model conversation in advance.
5. At the debrief, quote two of my phrases: one successful choice and one worth improving. Check factual accuracy, language, register and whether the next step was clear. Give up to three focused suggestions. Ask me to retry the weakest turn; wait. Only then offer an alternative wording and a harder replay.
Use voice replies when available. If I prefer selections, offer four plausible spoken replies and explain my choice before continuing. Do not require written compositions.

Lesson 05: Communicating outage plans and status
Original fictional case: Electrician Imani reviews an outage request with facilities coordinator Joel. The request proposes 18:00-19:00 for reception lighting only. Facilities has not approved it. A draft tenant notice incorrectly says the whole floor will be unavailable. No isolation status is supplied. Imani and Joel need to correct the notice scope and its proposed status without presenting the window as confirmed or giving operational instructions.
Language workshop: Correcting the proposed outage notice
Communication goal: Preserve the proposed scope and time window, correct an overstated notice, and distinguish facilities approval from electrical status.
Language guidance: The proposal is 18:00-19:00 for reception lighting only. Facilities approval is pending. The notice wrongly expands the scope to the whole floor. Correct both the affected service and the unapproved status; do not call the request a confirmed outage.
Useful expressions (preserve the supplied facts): The request proposes 18:00-19:00. / The scope is reception lighting only. / Facilities has not approved the request. / The draft notice incorrectly says the whole floor will be unavailable. / Replace that impact claim with reception lighting only. / Keep the window labeled proposed, not confirmed. / We need accurate scope and accurate approval status. / The request does not include every service on the floor. / The proposed start is 18:00 and the proposed end is 19:00. / The request gives no verified isolation status. / A notice is not an electrical operating instruction. / This discussion does not authorize issuing a final notice. / Proposed window, pending facilities approval. / Reception lighting only, 18:00-19:00, approval pending. / The corrected wording still needs the relevant review and release process. / No confirmed outage or operational clearance is established here.
Vocabulary: outage request: Proposal for an interruption of a defined service. / proposed window: Suggested period not yet approved or confirmed. / reception lighting: Lighting serving the reception area. / affected service: Particular function covered by the proposed interruption. / impact scope: Extent of the service or area affected as described. / tenant notice: Communication informing occupants of a relevant building arrangement. / draft notice: Preliminary communication not yet treated as final. / facilities approval: Acceptance through the responsible facilities process. / approval status: Whether a proposal is accepted, pending, or rejected. / confirmed window: Time period explicitly agreed through the relevant process. / planned interruption: Intended break in service delivery. / isolation: Separation from relevant energy sources through the applicable authorized process. / isolation status: Verified state under the applicable electrical procedure. / operational instruction: Direction to perform an equipment or system action. / notice correction: Amendment of inaccurate communication. / whole-floor impact: Claim that an entire floor is affected. / service boundary: Limit of the functions included in the request. / kilowatt-hour: Unit of energy equal to one kilowatt sustained for one hour. / pending approval: Awaiting a decision rather than accepted. / communication release: Authorization or controlled action to issue a notice. / scope readback: Repetition of the exact extent of a proposal. / status qualifier: Wording showing the level of certainty or approval. / authorization: Permission for a specified action through the relevant process. / revision record: Note showing how a communication or document changed.
Speaking task: Read turns 1-10 with reception lighting only and proposed clearly stressed. Switch roles for turns 11-20; separate facilities approval, notice release, and electrical status. Check and read the corrected notice without turning its window into an operating instruction.
Partner: Joel: Facilities coordinator / Imani: Electrician
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: Complete the notice-review exchange. Retain the exact service and proposed time range, while making the approval limit explicit.
Model for comparison AFTER my attempt, not a response to give me first: Joel: Give me the final short read-back so I can compare it with the request before sending it to the next reviewer.
Imani: The scope readback is reception lighting only; proposed eighteen hundred to nineteen hundred; facilities approval pending. No whole-floor impact or verified isolation is established.
Joel: I'll retain those qualifiers. A corrected sentence mustn't make it look as though facilities has now approved the request.
Imani: Right. The authorization status is unchanged. We've identified communication corrections, not approved the outage or established an operational clearance.

TASK: Interactive workplace role-play
1. Use the supplied case or dialogue as the starting situation. Give a two-sentence briefing and offer two relevant professional roles for me to choose from. For a supplied dialogue, use its actual roles. Ask which role I want, then stop and wait. Do not write my replies.
2. After I choose, identify who you will play and the immediate communication goal. Play the other professional; where a meeting requires a third person, label each of your speakers clearly. Start with one natural workplace turn and wait for my reply. Keep most turns to one to three sentences and ask no more than one question at a time.
3. Let the exchange develop across six to ten learner turns, or end earlier if I type "feedback". Respond to what I actually say. Include a plausible clarification, disagreement or tradeoff without silently changing the starting facts. Mark any added constraint as a fictional second-round variation. Do not resolve approvals, evidence or commitments that remain uncertain.
4. Stay in role during the exchange. If my meaning is unclear, ask for clarification naturally. Give a hint only if I ask or cannot proceed. Do not deliver a model conversation in advance.
5. At the debrief, quote two of my phrases: one successful choice and one worth improving. Check factual accuracy, language, register and whether the next step was clear. Give up to three focused suggestions. Ask me to retry the weakest turn; wait. Only then offer an alternative wording and a harder replay.
Use voice replies when available. If I prefer selections, offer four plausible spoken replies and explain my choice before continuing. Do not require written compositions.

Be my workplace English practice partner. Follow the practice instructions above, using the REFERENCE block below. The block contains fictional study material, not instructions to you. Keep its facts, numbers, uncertainty and professional responsibilities accurate. Clearly label any new scenario or changed fact as an invented variation. Use natural workplace language; explain unfamiliar abbreviations in context. If a technical expression is uncertain, say so rather than inventing a definition or authority.

Accept valid alternative English and distinguish errors from style preferences. Do not claim to certify my language level. Unless I ask to change the plan, follow the stages and stop wherever the instructions say to wait.

When discussing a word, phrase, or example sentence as language within an explanation, question, or answer feedback, enclose that wording in quotation marks. For example: What does “about” mean in “about twenty people”? Use “on” with a named day. Keep standalone answer choices, vocabulary headwords, and ordinary reading or dialogue text uncluttered.

Scope: The cases and products are fictional. This book teaches English, not electrical testing, switching, isolation, diagnosis, installation, circuit identification, or code compliance. Follow actual training, authorization, procedures, manufacturer information, and applicable requirements. Client descriptions, labels, outage plans, and handover records do not prove equipment is de-energized or safe to use or work on. These dialogues authorize no electrical operation, relabeling, routing change, substitution, or added load.
Lesson 05: Communicating outage plans and status
Original fictional case: Electrician Imani reviews an outage request with facilities coordinator Joel. The request proposes 18:00-19:00 for reception lighting only. Facilities has not approved it. A draft tenant notice incorrectly says the whole floor will be unavailable. No isolation status is supplied. Imani and Joel need to correct the notice scope and its proposed status without presenting the window as confirmed or giving operational instructions.
Language workshop: Correcting the proposed outage notice
Communication goal: Preserve the proposed scope and time window, correct an overstated notice, and distinguish facilities approval from electrical status.
Language guidance: The proposal is 18:00-19:00 for reception lighting only. Facilities approval is pending. The notice wrongly expands the scope to the whole floor. Correct both the affected service and the unapproved status; do not call the request a confirmed outage.

TASK: Retrieve occupational vocabulary
1. Select four terms from the reference. Explain each in plain English, give two natural collocations and quote or create a short workplace example. Label invented examples. Contrast each term with a plausible confusable term; acknowledge regional variation.
2. Present one role-labelled exchange with one missing word or phrase and four choices A-D. Exactly one choice must fit the stated facts and grammar. Stop and wait for my answer before revealing it.
3. Explain all four options, then invite me to read the completed exchange aloud. Offer a sentence frame for optional spoken practice, never an open-ended writing assignment.
4. Repeat for the other three terms, one question at a time. Vary the correct letter and the situation; preserve the reference facts. If a choice is ambiguous, replace the item.
5. Finish with two new four-choice collocation questions for later review, with a clearly separate answer key. Do not claim to schedule a reminder.

Lesson 06: Reporting findings and uncertainty
Original fictional case: Client Mira reported occasional flickering in display bay 2. Electrician Ellis has a visit note stating that flickering was not observed during the visit. No cause is established, and the technical report is pending review. Mira asks whether the installation is now fault-free. Ellis must explain the limited finding without dismissing the earlier report, inventing a repair, or asserting that the installation is safe or free of defects.
Language workshop: Not seen today is not fault-free
Communication goal: Distinguish a reported intermittent symptom from a limited visit observation and avoid turning a pending report into an unsupported assurance.
Language guidance: Mira reported occasional flickering, while the visit note says none was observed during that attendance. Those statements do not contradict each other. The note does not prove that the symptom never occurs, that a cause has been identified, or that a repair has been completed.
Useful expressions (preserve the supplied facts): You reported occasional flickering in display bay 2. / Flickering was not observed during the visit. / That statement applies to the visit observation period. / An occasional symptom may not appear during every visit. / The note does not show that your earlier report was wrong. / No cause has been established. / The technical report is pending review. / I cannot turn that note into a fault-free claim. / No completed repair is established by this information. / Not observed is an observation statement, not a diagnosis. / The note does not establish operational clearance. / The reported symptom concerns display bay 2. / No flickering observed during this visit; cause unresolved. / Occasional does not provide a precise interval. / Your report remains recorded, the visit observation is limited, and review is pending. / I can explain the record, but I cannot promise the issue is absent.
Vocabulary: flickering: Visible variation in light output perceived as fluctuating light. / intermittent symptom: Problem that appears at intervals rather than continuously. / display bay: Defined display area within a premises. / visit note: Record of information from a particular attendance. / observation period: Time during which a condition was observed or monitored. / not observed: Wording stating that a condition was not seen during the specified period. / reported history: Earlier account of events or symptoms. / technical report: Document recording the relevant professional information and findings. / pending review: Awaiting examination or approval through the relevant process. / established cause: Explanation supported by the relevant assessment. / fault-free claim: Assertion that no faults are present. / evidence limit: Boundary of what the available information supports. / repeat occurrence: Another instance of a previously reported symptom. / observation finding: Statement about what was seen during an examination or visit. / diagnostic conclusion: Conclusion identifying a technical problem or its cause. / repair record: Documentation of work actually carried out to correct an issue. / defect: Condition that fails an applicable requirement or expected function. / operational clearance: Authorization or verified status for use under the actual process. / qualified statement: Claim limited to the scope supported by the evidence. / absence of evidence: Lack of a finding, not automatically proof that a condition is absent. / symptom frequency: How often the reported condition occurs. / review outcome: Result of the relevant report assessment. / case status: Current stage of the reported issue and its follow-up. / unsupported reassurance: Comforting claim not established by the available evidence.
Speaking task: Read turns 1-10, retaining Mira's report alongside the limited visit observation. Switch roles for turns 11-20; stress not observed rather than fixed or fault-free. Check and read the transfer. Keep review pending and the cause unestablished.
Partner: Mira: Client / Ellis: Electrician
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: Complete the client summary. Retain the intermittent history, the visit-specific observation, the unknown cause, and pending review.
Model for comparison AFTER my attempt, not a response to give me first: Mira: Does that summary give anyone permission to use or work on the equipment? I want to be careful with words like cleared.
Ellis: It gives no operational clearance. The actual authorized process governs those questions; this conversation isn't permission for an electrical action.
Mira: I'll tell the manager the cause remains unresolved and review is pending. I won't call it fixed or fault-free from this note.
Ellis: That preserves the case status. Your report stays alongside the limited observation, and no unsupported diagnosis or repair claim closes the issue.

TASK: Choose grammar that preserves the meaning
1. Use the lesson's language workshop, or one actual sentence from the dialogue, to explain a single grammar distinction in no more than 90 words. Show how it affects timing, certainty, responsibility or politeness.
2. Give one brief occupational exchange containing a gap and four complete options A-D. Supply enough context for exactly one answer. Keep distractors plausible; distinguish grammar errors from wording that changes the facts. Stop and wait.
3. Explain why each choice fits or fails, then ask me to read the completed exchange aloud. Do not request a draft, original written sentence or essay.
4. Repeat with three new exchanges, one at a time, moving from recognition to a more subtle meaning contrast. Do not copy the published checks. Label invented variations and do not turn uncertainty into a promise.
5. End with a short contrast table and two supported spoken turns using supplied frames. Accept accurate alternatives in oral practice; acknowledge and replace ambiguous multiple-choice items.

Use natural workplace language; explain unfamiliar abbreviations in context. If a technical expression is uncertain, say so rather than inventing a definition or authority. Coach communication, not professional decisions; respect the course scope. Ask only for fictional or anonymized practice details. Judge clarity, meaning, appropriate tone and the next step. Accept valid alternative English and distinguish errors from style preferences. Do not claim to certify my language level. Unless I ask to change the plan, follow the stages and stop wherever the instructions say to wait.

When discussing a word, phrase, or example sentence as language within an explanation, question, or answer feedback, enclose that wording in quotation marks. For example: What does “about” mean in “about twenty people”? Use “on” with a named day. Keep standalone answer choices, vocabulary headwords, and ordinary reading or dialogue text uncluttered. Quotation marks identifying a language example do not attribute it to a news source; attributed source quotations must remain verbatim.

Practice setting: B2 independent. Use natural professional English with brief explanations. Let me attempt each task without a model first. Offer a hint after difficulty and invite a more precise retry.

REFERENCE
Course: Electricians' Workplace English
Professional audience: Electricians, electrical apprentices in supervised communication roles, electrical crew leads, and service coordinators
Scope: The cases and products are fictional. This book teaches English, not electrical testing, switching, isolation, diagnosis, installation, circuit identification, or code compliance. Follow actual training, authorization, procedures, manufacturer information, and applicable requirements. Client descriptions, labels, outage plans, and handover records do not prove equipment is de-energized or safe to use or work on. These dialogues authorize no electrical operation, relabeling, routing change, substitution, or added load.
Lesson 07: Assessing added equipment and substitutions
Original fictional case: After electrical scope is agreed for a café, owner Hana adds a second espresso machine and asks electrician Luis to include it at the original price and completion date. Equipment data for the added machine are unavailable. Luis can request the data and arrange a revised assessment and quotation. Electrical capacity and installation requirements are not established. The discussion must not assume the new machine matches the first, fits the existing provision, or can be added without cost or schedule effects.
Language workshop: A second machine changes the question
Communication goal: Request missing equipment information and explain the need for revised assessment and quotation without confirming capacity, price, or timing.
Language guidance: The second machine is a scope addition, not an already assessed part of the original work. Equipment data are missing, so capacity and installation requirements remain unknown. The machine category alone does not establish that it matches the first unit.
Useful expressions (preserve the supplied facts): You want to add a second espresso machine. / That machine was added after the electrical scope was agreed. / We do not have the equipment data for the added unit. / Please provide the relevant product information through the usual project process. / I cannot assume it has the same requirements as the first machine. / Available capacity has not been established for the addition. / The installation requirements still need assessment. / I can arrange a revised assessment and quotation. / I understand you want to keep the original price. / I cannot confirm unchanged cost for the added machine. / I understand the original completion date matters to you. / I cannot promise the same date before the change is assessed. / Technical suitability and commercial terms both remain open. / This information request does not authorize connection or testing. / Second machine requested; data missing; capacity, requirements, price, and timing unresolved. / We need the data for the revised assessment and quotation.
Vocabulary: equipment data: Product-specific technical information needed for assessment. / espresso machine: Coffee-making equipment forming the added request in this case. / additional load: Extra electrical demand associated with added equipment. / rated input: Manufacturer-stated input requirement under specified conditions. / nameplate: Product marking showing identification and relevant ratings. / manufacturer specification: Technical requirements or attributes supplied by the manufacturer. / supply requirement: Electrical supply characteristics required by the equipment. / capacity assessment: Evaluation of whether the relevant provision can meet the proposed demand. / existing provision: Electrical arrangement already included or available for the project. / installation requirement: Condition or detail needed for the specified installation. / revised assessment: Updated review accounting for changed information or scope. / revised quotation: Updated price proposal for the changed defined work. / original scope: Work included before the new request. / scope addition: Extra item proposed after the agreed scope. / active power: Electrical power associated with net energy transfer, expressed in watts or kilowatts. / price commitment: Agreed promise about cost. / schedule impact: Effect of a change on timing. / technical suitability: Whether the proposed arrangement meets relevant technical needs. / product substitution: Replacement of a specified item with a different product. / like-for-like claim: Assertion that a replacement or addition has equivalent relevant characteristics. / apparent power: For a single-phase load, RMS voltage times RMS current, expressed in volt-amperes. / approval boundary: Limit of what has actually been authorized. / change request: Proposal to alter the agreed work or requirements. / assessment outcome: Result reached after the required review.
Speaking task: Read turns 1-10, separating a machine category from product-specific data. Switch roles for turns 11-20; distinguish requested price and date from commitments. Check and read the handoff without inventing capacity, ratings, or a quotation.
Partner: Hana: Café owner / Luis: Electrician
Guided response task: Select supplied answers for the dialogue gaps. Check the explanations, then read the completed exchange aloud; no original writing is required.
Optional second-round challenge: Complete the café update. Keep the missing information, changed scope, review route, and unresolved commercial terms visible.
Model for comparison AFTER my attempt, not a response to give me first: Hana: What can I tell the coordinator today? I need a next step, not a message saying you've rejected it or agreed to fit it.
Luis: Say the change request needs product information, revised assessment, and quotation. Capacity, installation requirements, cost, and completion timing are still to be established.
Hana: I'll arrange the product documents through the team. My preferred price and date remain requests until the revised review establishes the terms.
Luis: Thank you. The approval boundary remains clear: this conversation records the request and the next review steps, not approval to add equipment or a promise of unchanged terms.

TASK: Choose grammar that preserves the meaning
1. Use the lesson's language workshop, or one actual sentence from the dialogue, to explain a single grammar distinction in no more than 90 words. Show how it affects timing, certainty, responsibility or politeness.
2. Give one brief occupational exchange containing a gap and four complete options A-D. Supply enough context for exactly one answer. Keep distractors plausible; distinguish grammar errors from wording that changes the facts. Stop and wait.
3. Explain why each choice fits or fails, then ask me to read the completed exchange aloud. Do not request a draft, original written sentence or essay.
4. Repeat with three new exchanges, one at a time, moving from recognition to a more subtle meaning contrast. Do not copy the published checks. Label invented variations and do not turn uncertainty into a promise.
5. End with a short contrast table and two supported spoken turns using supplied frames. Accept accurate alternatives in oral practice; acknowledge and replace ambiguous multiple-choice items.

TASK: Interactive workplace role-play
1. Use the supplied case or dialogue as the starting situation. Give a two-sentence briefing and offer two relevant professional roles for me to choose from. For a supplied dialogue, use its actual roles. Ask which role I want, then stop and wait. Do not write my replies.
2. After I choose, identify who you will play and the immediate communication goal. Play the other professional; where a meeting requires a third person, label each of your speakers clearly. Start with one natural workplace turn and wait for my reply. Keep most turns to one to three sentences and ask no more than one question at a time.
3. Let the exchange develop across six to ten learner turns, or end earlier if I type "feedback". Respond to what I actually say. Include a plausible clarification, disagreement or tradeoff without silently changing the starting facts. Mark any added constraint as a fictional second-round variation. Do not resolve approvals, evidence or commitments that remain uncertain.
4. Stay in role during the exchange. If my meaning is unclear, ask for clarification naturally. Give a hint only if I ask or cannot proceed. Do not deliver a model conversation in advance.
5. At the debrief, quote two of my phrases: one successful choice and one worth improving. Check factual accuracy, language, register and whether the next step was clear. Give up to three focused suggestions. Ask me to retry the weakest turn; wait. Only then offer an alternative wording and a harder replay.
Use voice replies when available. If I prefer selections, offer four plausible spoken replies and explain my choice before continuing. Do not require written compositions.
