Semicolons and Compound Sentences

Semicolons and Colons

Semicolons

A semicolon is stronger than a comma but weaker than a period. It is used to link two independent clauses with similar ideas, or it can be used to avoid confusion when there are already too many commas in a sentence.

Today's cafeteria pizza looked questionable; I ate it anyway.

Reminder
You may see a transition word after a semicolon.
She wanted AirPods for Christmas; however, Santa brought her a sweater.

Example:

Use a semicolon to join two related independent clauses, creating a compound sentence.
