Dialogue tags are phrases placed before, in the middle of, or after dialogue. The purpose of dialogue tags is to attribute spoken words to a character.

Dialogue tags stay outside of the quotes and get separated by a comma. But other rules apply in different situations. See our How to Format Dialogue article for all of the specifics.
