What Does the “M” Mean on an RSVP Card? The Simple Answer Explained

That single, mysterious “M” on a wedding RSVP card has confused more wedding guests than you might expect.

You receive a beautiful wedding invitation, open the RSVP card, and notice a line that begins with “M ______”. Suddenly, a simple response feels like an etiquette test. Should you write “Maybe”? Is it asking for the number of guests? Does the letter have something to do with your meal selection?

Fortunately, the answer is much simpler than it first appears.

The “M” on a wedding RSVP card is the beginning of a courtesy title, and the blank space is where you complete the title and write your name. Depending on the title you use, you might write Mr., Mrs., Ms., or Miss.

💍 What Does the “M” Stand For?

The “M” stands for the first letter of a courtesy title used on traditional wedding RSVP cards.

For example, an RSVP card might say:

M __________________________

The guest would complete the line with the appropriate title and name, such as:

Mr. John Smith
Mrs. Jane Smith
Ms. Taylor Johnson
Miss Emily Brown

This format comes from traditional formal invitation etiquette, where guests’ names were commonly written with an appropriate honorific.

So, no, the “M” does not mean “Maybe,” and it isn’t asking you to indicate how many people will attend. It is simply the beginning of the name section on many formal wedding response cards.
