What is a coordinating conjunction?
A co-ordinating conjunction is a word or phrase that connects two or more equal grammatical elements.
It could connect two verbs in a sentence: The audience cheered and clapped at the end of the performance.
It could connect two nouns in a sentence: Would you like cake or ice cream for dessert?
It could connect two adjectives in a sentence: The holiday cottage was small yet welcoming.
It could connect two adverbs in a sentence: Slowly but surely, I made it to the top of the hill.
Coordinating conjunctions are also used to connect independent clauses together:
James wanted a piece of cake. He was on a diet. = James wanted a piece of cake, but he was on a diet.
It was a long journey. I am feeling very tired now. = It was a long journey, so I am feeling very tired now.
When two independent clauses are joined with a coordinating conjunction, a comma needs to be placed before the conjunction.
When a conjunction connects two independent clauses together, a compound sentence is created.
