What Does RSVP Stand For? (And What to Write Back)
RSVP stands for the French "répondez s'il vous plaît" — please reply. Here is what it means on a wedding invitation, how to respond, and what to do when there is no reply card.

The short answer
Répondez s'il vous plaît — French for "please reply." Say it plainly, in the first sentence, before anything else.
Why a French phrase is on an English invitation
Brief, genuinely interesting history. Keep it to a paragraph; nobody came for an essay.
What it means for you as a guest
You must reply, yes or no. A non-reply is not a no — it is a problem for someone counting chairs.
How to reply
By card, by link, by code, by phone. What to write in each case.
What "RSVP regrets only" means
Different instruction, different obligation.
Common variations on the card
"RSVP by," "kindly reply," "the favour of a reply is requested," "M___."
