Punctuation—The Colon (:) & the Semicolon (;)

Colons are used to:

  • introduce a list

  • present dialogue or a quote

  • explain or clarify the previous clause

Only capitalize the word following the colon when it begins a new, complete sentence or an independent clause.

Examples

To introduce a quote

To explain the previous clause

When not to use a colon:

  1. between a verb and its object

  2. between a preposition and its object

Semicolon Uses

Rules

Semicolons are used:

  • to join 2 independent clauses with transitional expressions

  • in lists already containing commas

A semicolon should indicate an audible pause, slightly longer than a comma.

The word following the semicolon is not capitalized.

Examples

To join 2 independent clauses instead of a conjunction

:Fluffy the cat greeting his owner while sitting on a laptop keyboard.

To join 2 independent clauses with transitional expressions

Fluffy the cat giving back his owner’s credit card.
