Comma Rules

The 4 basic comma rules (four i’s)

1. Items in a series- use commas to separate lists of three or more items, adjectives, etc.

2. Introductory phrases- use a comma to separate an introductory word or phrase from the rest of the sentence. 

3. Interruptions in a sentence- use commas to section out interruptions from the main sentence.

4. Independent clauses joined together- If you are combining two complete thoughts, you may add a comma and coordinating conjunction.

Introductory Phrases

Introductory phrases are phrases that add information to a sentences, but cannot stand alone. They are set off with a comma and have a natural pause.

Interruptions in a sentence

Commas can be used to separate phrases that interrupt a sentence.
If the interruption is adding information to a noun in the sentence, it is called an appositive phrase.

Examples:
John, the man next door, is a retired firefighter. (Appositive phrase)

Independent Clauses Joined Together

You can use a comma and a coordinating conjunction (FANBOY) to combine two Independent clauses.

You have to have a coordinating conjunction with your comma! Otherwise, it is not strong enough to combine to complete sentences.
