Cause and Effect Language
Cause and effect language shows the relationship between reasons and results. It is essential for academic writing, analysis, and clear argument.
Expressing cause
These words and phrases introduce the reason for something.
| Expression | Structure | Example |
|---|---|---|
| because | + clause | She left because she was tired. |
| since / as | + clause | Since it was raining, we stayed in. |
| due to / owing to | + noun phrase | The delay was due to heavy traffic. |
| because of / as a result of / on account of | + noun phrase | Because of the storm, flights were cancelled. |
| thanks to | + noun phrase (usually positive) | Thanks to her help, I passed. |
Expressing effect / result
| Expression | Structure | Example |
|---|---|---|
| so | + clause | It was late, so we left. |
| therefore / consequently / as a result / thus | Sentence connector | Sales fell. Consequently, staff were cut. |
| lead to / result in / cause | Verb + noun phrase | Stress can lead to health problems. |
| hence | Formal, + noun or clause | She missed the train; hence the delay. |
Formal vs. informal
| Informal | Formal equivalent |
|---|---|
| because | due to the fact that / owing to |
| so | therefore / consequently / as a result |
| because of | as a result of / on account of |
Global temperatures have risen significantly over the past century. This is largely due to increased greenhouse gas emissions. As a result, ice caps are melting, leading to rising sea levels. Consequently, coastal regions face growing flood risk.
'Due to' vs. 'because of': Strictly, 'due to' modifies a noun (The delay was due to fog), while 'because of' modifies a verb (We were delayed because of fog). In practice, this distinction is often ignored, but it matters in formal writing.
Tip: Check what follows: clause → use 'because/since/as/so'. Noun phrase → use 'due to/because of/as a result of'.
