Often a recipient of the Invitation sees the abbreviation RSVP and wonders how to decipher this word. It comes from the French language and basically means "Please, reply". The person or organization that sent you the invitation wants you to contact them and tell them whether you are able to attend the event in question. Typically, an Invitation will contain a phone number or e-mail address - you can text, call, or compose a short note to notify the sender you will be present. Additionally, you may inform the event organizer about your food preferences and the person you are bringing with you - but only if you are asked to provide this information.
