Initial request for an answer? (4)

I believe the answer is:

rsvp

(Other definitions for rsvp that I've seen before include "Answer the invitation briefly, please" , "Brief notation to say, answer the invitation" , "Please answer the invitation, monsieur" , "Can you come to the party?" , "Letters on an invitation" .)

I've seen this clue in the L.A. Times Daily, the LA Times and The Washington Post.
