Hyphen (-) vs. Dash (–/—): What’s the Difference?

What Is a Hyphen (-)? What Is a Dash (–/—)?

 a hyphen (-) is a small punctuation mark used to join words, create compound adjectives or indicate a break in a word. It never indicates a pause and is generally structural in nature.

a dash (– or —) is longer and indicates a range, a link or contrast or a break or dramatic emphasis in a sentence. Dashes control the rhythm of a sentence and allow writers to create clarity or emphasis.

There are two types of dashes:

En dash (–): used for ranges (2010–2024), relationships and contrasts.

Em dash (—): used for a break in thought, emphasis, interruption or aside information.
