What does RSVP mean?
RSVP stands for the French phrase répondez s'il vous plaît, meaning please reply. It is used on invitations to ask guests to say whether they will attend.
The phrase became popular in English-speaking countries in the 1800s, when French was used in polite society for etiquette. On invitations, RSVP is usually followed by a date and a way to respond, such as a phone number, email address or response card.
Responding helps hosts plan food, seating and other arrangements. Etiquette experts say guests should reply whether they will attend or not, and soon after receiving the invitation. Writing please RSVP is technically redundant, since RSVP already includes please, but it is commonly used.
