A colon (:) is a type of punctuation that introduces lists, explanations, dialogue, and quotations. It can also be used in titles, to indicate the time of the day, and in business or formal correspondence.

How to Use Colons

Colons and Lists

Colons can be used to introduce lists and examples if the preceding information is a complete sentence. You can also use phrases like “as follows” or “the following” to introduce a list.
