compound sentence

A compound sentence has two or more independent clauses in it. Every compound sentence will have either a FANBOYS in it or a semi-colon which joins the two clauses. If a FANBOYS is used, it must be preceded by a comma. A compound sentence will never have a dependent clause in it.

• Jeb drove to the seminary, but Joe Note the FANBOYS conjunction here! accidentally drove into a tree.
• I love books; Jeb When both clauses are very closely related, it is permitted to forego the FANBOYS conjunction with a comma and to use a semi-colon instead. does not.
• My wife is a very avid cook, so I Note the FANBOYS conjunction here! decided to purchase a commercial duty mixer for her.

The following sentence is simple. The reason it is not compound is that both verbs “went” and “forgot” are governed by the same subject “Jeb”. Hence, there are not two independent clauses here but only one independent clause with two verbsThis is called a 'compound predicate'.. Notice also that there is no comma.

Jeb went to the store yesterday to get some milk but forgot to purchase some Canola oil.
