What is the full form of RSVP in Hindi?

There is no direct translation of "RSVP" in Hindi. It's a French abbreviation that stands for "Répondez s'il vous plaît," which translates to "Please reply."

However, in Hindi, you can use these phrases to convey the same meaning:

* कृपया उत्तर दें (Kripya uttar den): This is the most direct translation of "Please reply."

* अपना उपस्थिति की पुष्टि करें (Apna upasthiti ki pushti karen): This means "Please confirm your presence."

* आप आ रहे हैं या नहीं, बताएं (Aap aa rahe hain ya nahin, bataen): This means "Please let us know if you are coming."

Ultimately, the best way to handle an RSVP in Hindi would be to use the context of the invitation and choose the phrase that best fits the situation.
