What are coordinating conjunctions?
Conjunctions are joining words that link together parts of a sentence. The three main coordinating conjunctions are ‘and’, ‘but’ and ‘or’.
They can be used to join together two clauses in a sentence. However, the clauses need to make sense on their own. For example:
I had a terrible cold. I still went to work.
You can add the coordinating conjunction ‘but’ in between these causes so the sentence reads:
I had a terrible cold but I still went to school.
Remember though, you can often leave out the subject word in the second coordinating clause. For example:
I had a terrible cold but still went to school.
In this example you can remove the word 'I' from the second coordinating clause.
