Grammar Warm-up: Colon Definition: “The most important thing to remember about colons (:) is that you only use them after statements that are complete sentences…[Usually] the items after the colon expand on or clarify what came before the colon…[Finally,] never use a colon after a sentence fragment” (Grammar Girl).

Examples:
