Commas in Compound Sentences

A compound sentence is a sentence that contains at least two independent clauses joined by a coordinating conjunction.

Coordinating conjunctions are words that connect words, phrases, or clauses. The most common ones are: for, and, nor, but, or, yet, so (FANBOYS).

The comma goes before the coordinating conjunction that joins the two independent clauses.

I like ice cream, and I like cake.

The comma helps to clarify the separation between two independent clauses.

True.

Yes, it should be: 'I wanted to go to the park, but it was closed.'

She loves to dance, but she is shy.

but.
