When Is It Proper to Use a Semicolon?

A semicolon is most commonly used to link (in a single sentence) two independent clauses that are closely related in thought. When a semicolon is used to join two or more ideas (parts) in a sentence, those ideas are then given equal position or rank.

When should a semicolon be used examples?

Here's an example: I have a big test tomorrow; I can't go out tonight. The two clauses in that sentence are separated by a semicolon and could be sentences on their own if you put a period between them instead: I have a big test tomorrow.

When should you use a semicolon instead of a comma?

Rule to Remember

Use a semicolon to replace a comma when you use a coordinating conjunction to link independent clauses that already contain commas. In this example, using a semicolon makes it easier to read the two independent clauses on either side of the coordinating conjunction: Correct: My dog is sick.
