Concept #09: Causal Phrases
This rebuilt lesson keeps the original concept image, tightens the structure, and turns the explanation into a clearer self-study guide.
Core Idea
Causal phrases are used to communicate the cause and effect relationship between two actions or events. This concept is essential for conveying how one event leads to another. There are three basic sentence styles used to express causation:
Key Points
- A causes B
- A is caused by B
- B is caused by A
Causal Direction: A ➡️ B (Cause ➡️ Effect)
Let’s explore the different ways to express causation in English, as illustrated in the image.
Sentence Styles and Phrases
1. A causes B
In this structure, the first event (A) causes the second event (B). This is a direct way to show causation.
- This causes: “The heavy rain causes flooding in the area.”
- This creates: “Pollution creates health problems for many people.”
- This produces: “The new policy produces positive outcomes for the company.”
- This leads to: “Lack of exercise leads to obesity.”
- As a result: “The team worked hard. As a result, they won the championship.”
- This results in: “The accident results in traffic delays.”
- Consequently: “The company failed to innovate. Consequently, it went bankrupt.”
2. A is caused by B
In this structure, the second event (B) is the cause of the first event (A). This is useful for emphasizing the cause.
- Is caused by: “Flooding is caused by heavy rain.”
- Is created by: “Health problems are created by pollution.”
- Is produced by: “Positive outcomes are produced by the new policy.”
- Is a product of: “Obesity is a product of lack of exercise.”
- Is a result of: “The championship win is a result of the team’s hard work.”
- Is due to: “Traffic delays are due to the accident.”
- Is a consequence of: “The bankruptcy is a consequence of the company’s failure to innovate.”
3. B is caused by A
This structure is less common but still important. It is often used in scientific or technical contexts to describe results.
- Is affected by: “The climate is affected by greenhouse gas emissions.”
- Is a contributing cause of: “Smoking is a contributing cause of lung cancer.”
Examples and Explanation

Additional Examples

Conclusion
Understanding and using causal phrases correctly helps in clearly conveying the cause and effect relationship in sentences. This is particularly important in both spoken and written English for explaining processes, giving reasons, and discussing results. By practicing these structures, non-native speakers can improve their ability to express complex ideas effectively.
Practice Exercises
- Create sentences using “This causes,” “As a result,” and “Consequently.”
- Rewrite the following sentences to use the “is caused by” structure:
- “The company’s success is due to its innovative products.”
- “Obesity is a result of poor dietary habits.”
- Use the “Due to A, B” structure in your own sentences.
By practicing these exercises, you can become more comfortable with expressing causation in English.
