Semicolons and Colons

Semicolons and colons are punctuation marks that help clarify relationships between clauses or items in a list. Correct usage improves readability and precision in writing.

Semicolons (;)

A semicolon connects closely related independent clauses or separates items in a complex list.

• Use a semicolon between independent clauses not joined by a conjunction: I went to the store; it was closed.
• Use a semicolon to separate items in a list when items already contain commas: We visited Paris, France; Rome, Italy; and Berlin, Germany.

Colons (:)

A colon introduces lists, explanations, quotations, or emphasizes information.

• Introduce a list: Bring the following items: a pen, a notebook, and a ruler.
• Introduce an explanation or elaboration: He had only one hobby: collecting stamps.
• Introduce a quotation: She said: "I will be there soon."
• Emphasize a word or phrase: Remember this: practice makes perfect.

Rules / Guidelines

• Do not use a semicolon before a conjunction (use a comma instead).
• Do not capitalize the first word after a colon unless it is a proper noun or starts a complete sentence (style dependent).
• Colons should follow an independent clause.

Examples

Semicolons: I have a meeting tomorrow; I cannot attend the party.
Semicolons in complex lists: On our trip we visited Paris, France; Rome, Italy; and Berlin, Germany.
Colons for lists: You will need three items: a pen, a notebook, and a ruler.
Colons for explanation: She had one goal: to win the championship.
Colons for quotations: He reminded us of Shakespeare: "To be, or not to be, that is the question."
