How to Use a Semicolon Correctly (3 Rules)

A semicolon has three main uses: joining two closely related complete sentences, coming before transitions like "however" between sentences, and separating list items that already contain commas.

Rule 1: Join related sentences

"I finished the report; it took all weekend." Both sides could stand as separate sentences.

Don't use a semicolon if one side is not a complete sentence: "Because I was tired; I went home" is wrong.

Rule 2: Before a transition

"The plan was risky; however, it worked." Put a comma after the transition word.

Other transitions: therefore, moreover, consequently, otherwise.

Rule 3: Complex lists

"We visited Paris, France; Rome, Italy; and Lisbon, Portugal." The semicolons prevent confusion.

This is the only case where items on either side need not be complete sentences.

Semicolon vs colon

A colon introduces something (a list, explanation or quotation); a semicolon links equals.

If in doubt, a period is always safe.

Frequently asked questions
