Learn English – “Sign up” vs. “signup”


When we have a button on a website for creating an account, should it say "sign up" or "signup"?

I see "sign up" in most places, but which is the correct one?

Best Answer

It should be sign up, as that is the verb form (see definition 30). Signup (or sign-up) is a noun.

That pattern usually holds: log in (verb) vs. login (noun), sit up (verb) vs. situp (noun), etc.
