Question

How does a hyphen differ from a dash?

Answer 1

A hyphen joins two or more words together while a dash separates words into parenthetical statements. The two are sometimes confused because they look so similar, but their usage is different. Hyphens are not separated by spaces, while a dash has a space on either side.

Hope this helps. 

Answer 2

A hyphen joins two words together, whereas a dash separates ideas and statements. <span />
