An RSVP card is a small card included with invitations, typically for events like weddings or parties. It allows guests to confirm their attendance by providing a simple way to respond. The card usually includes options for guests to indicate whether they will attend, along with space for their names and any dietary preferences. The term "RSVP" comes from the French phrase "Répondez s'il vous plaît," meaning "Please respond." This card helps the event host plan accordingly, ensuring they have enough seating, food, and other arrangements for the guests who will attend.
