RSVP may refer to:
"Répondez s'il vous plaît", a French phrase that translates to "reply, please." or literally "reply, if it pleases you". It is with this meaning that invitation cards and similar documents are often marked with "R.S.V.P." It is standard practice to reply to an RSVP request whether confirming attendance or declining.
Do we RSVP everytime we received an invitation? Thought so lah …
