Have you ever received a wedding RSVP card and wondered what you are supposed to write after the mysterious “M”? It may look confusing at first, but the answer is quite simple. The “M” is traditionally the beginning of a courtesy title, such as Mr., Mrs., Ms., or Miss, followed by the guest’s name.

For example, you might complete the line as “Mr. John Smith,” “Mrs. Jane Smith,” or “Ms. Taylor Jones.” The “M” is not asking about your meal choice, marital status, or how many guests you plan to bring. It is simply a traditional way of prompting you to provide the name of the invited guest.

If you use a title that does not begin with “M,” you do not have to force yourself into one of the traditional options. You can write the title you normally use or simply provide your name if you prefer. The most important thing is that the couple can clearly identify who is responding and who is expected to attend.

The tradition comes from older invitation and etiquette practices, when formal titles were commonly used on social correspondence. Today, many couples choose simpler wording because it is more inclusive and easier for guests to understand. Instead of an “M” followed by a blank line, invitations can simply say “Name:” or “Names:” and avoid the confusion altogether.

So, the next time you see that little “M” on an RSVP card, there is no secret meaning behind it. It is simply a prompt for your courtesy title and name. Complete it with the form you prefer, check the rest of the RSVP carefully, and send it back by the requested deadline.
