What does RSVP Mean?

The term R.S.V.P. is from the French expression ‘répondez s’il vous plaît’, meaning ‘please respond’. R.S.V.P. is added to invitations when a reply is needed by the sender to know if someone is attending the event or not. Responses to the RSVP help the sender get an accurate count of those that will attend in order to plan.
