Because and so

February 15, 2017 - pdf

One conjunction is enough to join two clauses. We do not normally use two.

Because I was ill, I took a day off.

OR

I was ill so I took a day off.

The conjunction ‘because’ is used to express the cause/reason. The conjunction ‘so’ is used to express the effect/result.

Don’t use both because and so in a sentence.

Do not write: Because I was ill, so I took a day off.

Incorrect: Because she was fat, so she couldn’t run fast.

Correct: Because she was fat, she couldn’t run fast.

Correct: She was fat, so she couldn’t run fast.

Complete the following sentences using so or because.

1. ……………….. I loved him, I tried to save him.

2. I loved him, ……………….. I tried to save him.

3. I was not feeling well, ……………….. I decided to consult a doctor.

4. We lost the contract ………………… we couldn’t complete the project.

5. We came back ………………… dad fell ill.
