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?

    I have never seen 'signup'; could you provide a link to a place where it appears?

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.

    Another illustrative example is "Checkout", meaning "proceed to the CHECKOUT screen" or "initiate a process called CHECKOUT". "Checkout" is fine by itself, but wrong if next to a button that offers the alternative "Continue Shopping". In that case, for consistency, the button should say "Check Out" (or{Go|Proceed} to Checkout). Commented Oct 1, 2017 at 19:38
