ms.
Synonym discussion
Sense: noun/1
Ms., Miss, Mrs., and Mx. are all titles placed before a name, but they signal different things. Ms. is the most neutral choice because it does not show whether a woman is married, so it is widely used in letters, forms, business settings, and introductions when marital status is unknown or irrelevant. Miss often suggests a younger or unmarried woman and can sound more traditional. Mrs. normally marks a married woman and is often followed by a family name. Mx. is a newer gender-neutral title for people who do not want a specifically female or male title. For example, a school email may say 'Ms. Emma Lin', while a form may ask whether someone prefers Ms., Mrs., Miss, or Mx.
Etymology
Ms. became established in English as a title for a woman that does not reveal marital status, developing alongside the older titles Miss and Mrs. It spread widely in American English during the 20th century, especially in business and official writing. The same written form is also used for several unrelated abbreviations, including manuscript, multiple sclerosis, Master of Science, and the postal code for Mississippi. Because of that, modern ms. is not one single historical line, but a group of short forms that happen to share the same letters and punctuation.
