Ms. is an English-language honorific used with the last name or full name of a woman, intended as a default form of address for women regardless of marital status. The term Ms. has its origins in the female English title and was first suggested as early as 1901. It is a general title that does not indicate marital status but is still feminine. Mrs. is a traditional title used for a married woman. Miss is a traditional title used for an unmarried woman. Mx. is a title that indicates neither marital status nor gender.

Here are some key differences between these titles:

• Ms.: This title is used when you are not sure of a womans marital status, if the woman is unmarried and over 30, or if she prefers being addressed with a marital-status neutral title. It is intended to be neutral, in that it can be used for married and unmarried women alike.

• Mrs.: This title is used when addressing a married woman.

• Miss: This title should be used when addressing a young, unmarried woman. Most older women who are unmarried prefer to go by "Ms.," though this often comes down to personal preference.

Its important to note that the best title to use always comes down to the womans preference.
