Common Questions Concerning Use

Despite the above information concerning the use of these titles, there are plenty of questions and misconceptions beyond their official definitions. We are addressing some of those below, so you are comfortable with the official forms of use in writing. 

Ms. vs. Mrs. Etiquette: When Ms. Is A Preferred Title

Since Ms. and Mrs. can be used as interchangeable terms, you might wonder what the proper etiquette rule is based on marital status. Mrs. is the incorrect title for a single woman, but Ms. can be used as an official title for married and unmarried women. So, how do you know which is the preferred title?

The answer is to ask what personal preference a woman would like used. Ms. is often used as a more formal form of address in a professional setting or as a professional title to help distinguish a woman from her husband. Since it can also be a more respectful use for a mature, single woman, it is best to ask to avoid any disrespect. If asking is not possible, Ms. is generally accepted as a neutral term and is, in fact, more popular to use due to this.

Why Is There an R in Mrs.?

If Mrs. is an abbreviation of missus, then where does the “r” come from? Remember, missus is a variation of mistress, and so Mrs. represents the original formal title form. 

What is Proper Wedding Invitation Wording?

Mr. Mrs. Ms. and Miss – Full Form Meaning 1

When addressing envelopes for wedding invitations, or similar formal events, you want to make sure you use what you have learned about the differences between Ms., Mrs., and Miss. When addressing a married couple, you will use both the respective titles of Mr. and Mrs. followed by the surname. If only inviting the woman, use Mrs., and if unsure of marital status, default to the form Ms.

When inviting an unmarried couple, use the man’s name first following Mr., followed by the woman’s name with Ms.: for example, Mr. John Smith and Ms. Holly Doe.

For young women under 18, include Miss. before their name.   

Why Do I Sometimes See Ms., Mrs., Miss., and Mr. Without Periods?

You may sometimes see these terms used without a period and wonder which is correct. American English uses a period, while British English does not. If you see the use without periods, you are most likely reading a British publication. Depending on where you live, you want to adapt the use to what is appropriate and not mix the two uses.

Wrapping it Up

Overall these aren’t confusing rules to follow, and this article should serve as an official guide for you to refer to when looking for the respective titles of both married and single men and women, as well as young adults and children.
