You must have noticed this abbreviation used extensively in wedding cards or another sort of invitation–r.s.v.p. Usually, this is followed by the name of the person who is sending the invitation or the main person who is responsible for the organizing of the party/feast, etc.
RSVP is a French abbreviation, which expands like this: “répondez s’il vous plaît“. In English, this simply means “respond, if you please.” Now, the context here is that a person is expecting a sort of confirmation from your side whether you would be able to come to the occasion or not.
So, if you are looking to know the meaning of rsvp in Punjabi or want to know its full form, just know that it means ਕ੍ਰਿਪਾ ਕਰਕੇ ਉੱਤਰ ਦਿਓ।
