MS

A common way to abbreviate Microsoft, such as "MS Office" or "MS Word."

MS is an acronym for "middle school," which is where students get their lower, or junior, secondary education. The acronym is typically used online when typing to save on space and keystrokes.

In the United States, kids enter into middle, or junior high, school (grades 6 to 8 or 7 to 9) after they receive their primary education in elementary school. Middle school is the weirdest stage of school for many students because of puberty and all the awkwardness that follows. It usually continues on to high school (grades 9 to 12 or 10 to 12) where students receive their secondary education.

A prefix that identifies a person as a woman, but does not define her marital status.
