Unit 97 · Conjunctions and clauses
and but or so because
Study
We use these words (conjunctions) to join two sentences. They make one longer sentence from two shorter sentences:
sentence A The car stopped. — — The driver got out. sentence B
The car stopped and the driver got out.
and/but/or
| sentence A | sentence B | ||
| We stayed at home | and | (we)* watched television. | * It is not necessary to repeat 'we' and 'she'. |
| My sister is married | and | (she)* lives in London. | |
| He doesn't like her, | and | she doesn't like him. | |
| I bought a sandwich, | but | I didn't eat it. | |
| It's a nice house, | but | it doesn't have a garden. | |
| Do you want to go out, | or | are you too tired? |
In lists, we use commas (,). We use and before the last thing:
I got home, had something to eat, sat down in an armchair and fell asleep.
Karen is at work, Sue has gone shopping and Chris is playing football.
so (the result of something)
| sentence A | sentence B | |
| It was very hot, | so | I opened the window. |
| Joe does a lot of sport, | so | he's very fit. |
| They don't like travelling, | so | they haven't been to many places. |
because (the reason for something)
| sentence A | sentence B | |
| I opened the window | because | it was very hot. |
| Joe can't come to the party | because | he's going away. |
| Lisa is hungry | because | she didn't have breakfast. |
Because is also possible at the beginning:
Because it was very hot, I opened the window.
In these examples there is more than one conjunction:
It was late and I was tired, so I went to bed.
I always enjoy visiting London, but I wouldn't like to live there because it's too big.
