Compound Sentences with Coordinating Conjunctions (FANBOYS)

A compound sentence contains two separate subject and verb pairs. You can combine two simple sentences together with a comma and a coordinating conjunction to make one compound sentence. Here are some examples:

F – for I drank some water, for I was thirsty.
She put on a sweater, for it was cold outside.
*for means the exact same thing as because. The only difference is that when you use for to join two sentences together into one compound sentence, you need to use a comma before it. When you use because to join to sentences, you don’t use a comma before it.

A – and He was tired, and he had a headache.

N – nor She doesn’t drink milk, nor does she eat butter.

I can’t whistle, nor can I sing.
He didn’t study last night, nor did he read his book.
They were not wearing jackets, nor were they carrying umbrellas.
*nor means “also not”. Nor requires unusual grammar. The first sentence will contain a negative verb. The second sentence will contain what looks like an interrogative affirmative verb form. An auxiliary verb (do/does/did, is/am/are/was/were), modal verb (can/could/will/would/may/might/must/should), or be main verb (is/am/are/was/were) comes after nor and before the subject, and then the main verb comes after the subject.

B – but Tom studied a lot, but he didn’t pass the test.

O – or He can buy the book, or he can borrow it from the library.

Y – yet Tom studied a lot, yet he didn’t pass the test.

*yet means the same thing as but.

S – so Maria was thirsty, so she drank some water.

It was cold outside, so she put on a sweater.
