Do you "accept" or "except" an invitation?

A little morei

Accepting an invitation means saying yes to it. "Except" almost never works as a verb in everyday writing; it signals what's been left off a list. A quick test: swap in "welcome" — "welcome an invitation" reads fine, so "accept an invitation" is right.

• → What is the difference between "accept" and "except"? "Accept" means to receive or welcome. "Except" means to leave out. Opposite jobs, near-identical sound.
• → Is it "everyone accept me" or "everyone except me"? "Everyone except me." The word here marks who's left out — that's except.
• → Is "except" ever a verb? Rarely. In everyday writing, "except" is a preposition meaning "leaving out." The verb you probably want is "exempt" or "exclude."
