If you have ever received a wedding invitation, you may have stared at a small line that begins with a single letter: M_____. It looks like a riddle. Some people think it is asking for a first initial. Others think the “M” stands for meal. The answer is simpler. The printed “M” is the beginning of a courtesy title. Guests are meant to finish it as Mr., Mrs., Ms., or Miss, then write their name. John Smith would write Mr. John Smith. Jane Smith might write Ms. Jane Smith. The letter is not a question. It is the first character of the title that used to appear before every formal name.
The format comes from older stationery etiquette. Printers did not want to list every possible honorific on every card, so they started the line with “M” and left the rest blank. That one letter covers Mr., Mrs., Ms., and Miss. It has nothing to do with dinner. Meal choices, if they appear at all, sit in a separate section with checkboxes for chicken, beef, or vegetarian. Writing “meal,” a middle initial, or only the letter M again is not what the line is for.
What you should write depends on the title you actually use. A man who uses Mr. writes Mr. and his full name. A woman may write Mrs., Ms., or Miss according to her preference, not according to someone else’s idea of marital status. If you do not use a traditional title—if you prefer Dr., a gender-neutral honorific, or no title at all—do not force yourself into a letter that does not fit. Write your name clearly. If the card feels too rigid, a short note or message to the couple is better than a title that misrepresents you. RSVP comes from the French répondez s’il vous plaît, meaning please respond. Hosts need names and counts for catering, seating, and place cards, so a clear reply by the deadline matters more than perfect old-fashioned form.
Modern couples are already changing the habit. Many cards now say Name instead of M. Websites and email replies skip titles altogether. The traditional line is not wrong. It is simply a leftover from an era when every formal name began with a courtesy title. When you see that M, think of it as the start of the word, complete it if it fits, and move on. The invitation is asking who is coming, not testing whether you remember Victorian stationery.
