Teacher Tips for Using Cause and Effect Vocabulary
I’ve marked thousands of essays, and these are my top tips for boosting your writing score:
1. Avoid Repeating “Because” and “So”
❌ “People drive cars because it is easy, so cities are polluted.”
✅ “Urban pollution stems from the reliance on private cars, which results in poor air quality.”
2. Use Cause-and-Effect Chains for Cohesion
Create logical progressions:
“Fast food consumption leads to obesity, which in turn results in higher healthcare costs.”
This shows cohesion and improves your Coherence and Cohesion score.
3. Combine with Topic-Specific Vocabulary
Cause-and-effect vocabulary is powerful when paired with precise topics:
“Climate change arises from excessive greenhouse gas emissions, resulting in rising global temperatures.”

Notice how the paragraph:
