What Is the Proper RSVP Response?

Usually contained in an invitation to an event, an RSVP can be properly responded to by simply informing the requester of one's intentions to attend the event or not. RSVP is an abbreviation for the French phrase "répondez, s'il vous plaît," which translates to "please reply" in English. RSVP is often followed by another abbreviation--ASAP--meaning "as soon as possible," to encourage the invited party to respond as soon as possible.
