Rsvp stands for abbreviation in email

A common one!

RSVP stands for "Répondez S'il Vous Plaît", which is French for "Respond If You Please". It's a polite way to ask someone to confirm their attendance or response to an invitation, typically for an event or gathering.

In email, RSVP is often used as a shorthand way to ask someone to respond to an invitation, such as:

"Please RSVP by [date] to let us know if you can attend."

It's a common convention in formal and informal emails, and is often used in invitations for events like weddings, parties, conferences, and more.
