Q&A: RSVPs: What's the Meaning of "M"?
Q: What does the "M" mean on the first line of a response card? I'm assuming this is where I fill in our names, but why is the letter there? Is it an abbreviation for Mr./Mrs./Ms.?
A: In a sense. When you sign your name or names on that line, use the "M" as the first letter of your title. For example, you might write "Ms. Diana Barnes and Mr. Steven Brown." A married couple would put "Mr. and Mrs. Casey Harris." A single woman would put "Ms. Angela Hall." Just tack on the letter or letters to create the appropriate title, then fill in your names.
