What do semicolons do?

Semicolons can join two independent clauses together. Semicolons can separate items in a complex list (list already with commas).

Where are colons used in a sentence?

Colons can add single words, lists, or phrases to the end of already complete sentences.

Where are commas used in a sentence?

Commas go between 1) cities and states in an address, 2)day of the week and the month, and 3) in lists of three or more items.

Commas also set off different types of phrases and clauses. Examples include tag questions, prepositional phrases, introductory phrases, non-restrictive elements, and dependent clauses.

What is an appositive?

A nonessential element or nonrestrictive element is information that is not essential to the meaning of the sentence and is set apart with commas. Appositives specifically rename the thing it describes. When you take out a nonrestrictive element, the meaning of the sentence stays the same.

What are modifiers?

Modifiers are words, phrases, or clauses that describe, identify, or change the noun or pronoun they're modifying.
