Do you login or log in?

Which is correct?

Your Apple ID is the user name you use to _____ to iCloud, iTunes and the app store.

a. log in

b. login

Answer: a

Explanation:

The general rule is that the verb phrase is two words while the noun or adjective form is the single compound word. So you log in to something — as long as you can remember your login info.

Here’s a list from The Chipmunk of Doom. Ignore at your own peril.

Verb form is the first example in each case:

• set up vs. setup
• make up vs. makeup
• work out vs. workout
• pick up vs. pickup
• get up vs. getup
• turn out vs. turnout
• log in vs. login
• turn over vs. turnover
