Usage

What does umpire mean? An umpire is a kind of referee who enforces the rules during certain sports, such as baseball, softball, and cricket. In higher levels of baseball and softball, there are often multiple umpires on the field. They are primarily responsible for determining whether base runners are “safe” or “out.” The most important one is the home plate umpire, who determines whether each pitch is a “ball” or a “strike.”Umpire is also sometimes used to refer to someone who acts as an impartial judge during some kind of conflict, such as two friends having an argument, as in Jane and Mike were losing their tempers with each other at the meeting so I had to step in and act as an umpire until they calmed down. Less commonly, umpire can be used as a verb meaning to perform the duties of an umpire, as in I signed up to umpire my daughter’s softball games. An informal short form of umpire is ump, which can also be used as both a noun and a verb. It’s especially used as an informal way to address an umpire, as in Hey, ump, that was way out of the strike zone!Example: The umpire called him out, but I’m pretty sure he was safe.

Etymology

Origin of umpire

First recorded in 1350–1400; Middle English umpere, variant of noumpere ( a noumpere taken as an oumpere; cf. adder 1, apron), from Old French nomper, nonper “arbiter,” i.e., “one not equal.” See non-, peer 2

Explanation

An umpire is a kind of referee, an official whose job on the baseball or softball field is enforcing the rules of the game. You might hear an umpire yell, "Strike three! You're out!" When a conflict comes up during play, it's the umpire who mediates and ultimately makes an official decision. Umpire is also a verb, meaning to act as an umpire. The word comes from the Old French nonper or "odd number," which refers to a third person helping two others settle their differences.
