rsvp
word
Definition
The act of responding to an invitation to let the host know if you will attend an event. The term comes from the French phrase 'Répondez s'il vous plaît,' meaning 'please respond.'
Usage & Nuances
RSVP is used both as a noun and verb, mostly in formal or semi-formal invitations. You may see 'Please RSVP by...' or just 'RSVP'. It's common in English to say 'RSVP to the invitation'. Say 'I RSVP'd' (past), or 'Please RSVP'. Don't confuse with a regular reply; RSVP specifically means confirming attendance.
