Compound Sentences

Compound sentences are essentially two simple sentences - or main clauses - joined together by a link word.

A sentence can actually have two main clauses. And because they are main clauses, or independent clauses, neither clause depends on a word in the other clause.

It's really like writing two separate sentences on two separate pieces of paper and then joining them together with glue. The glue in this case are coordinating conjunctions.

Coordinating Conjunctions

Conjunctions are joining words. They join two clauses together to make two separate sentences into one big one. The clauses used to join main clause together are frequently and or but.

For example, 'The car started and we drove home.'


'It's a nice day today but tomorrow looks like it may rain.'

As we can see in both of the above examples, each clause could stand independently as a sentence. For instance, 'The car started,' is a complete sentence, as is, 'We drove home.'
