What is rsvp meaning?

RSVP is an acronym that stands for "répondez s'il vous plaît" in French which means "please respond" in English. It is a request for a reply to an invitation or event, whether the recipient is attending or not. RSVP is used by hosts to know how many people are likely to come to an event, who to expect, and what to prepare for. It also helps guests inform the host of any dietary restrictions or accessibility needs they may have. Proper etiquette requires guests to respond to an RSVP as soon as possible, usually within a week of receiving the invitation.
