What Is a Dash?
A dash is a punctuation mark. It sets off information that interrupts the flow of a sentence.
Writers use dashes in a lot of different situations. For example, they may use a dash to show a sudden break in a person’s thoughts. They may also use a dash in dialogue to show when one character’s speech is interrupted by another’s. Dashes help writers set off long explanatory statements, or statements that give more information about someone or something. They also help set off introductory lists.
Dashes Versus Hyphens
Though dashes and hyphens have a similar look, they serve different purposes. While dashes show interruptions in thoughts or speech, hyphens connect parts of words. Dashes are also longer than hyphens.
