Usage

What does ref mean? Ref is an informal and shortened way of referring to a referee, an official in a sporting event who enforces the rules of the game.In sports, refs do things like call fouls and stop play when there has been a violation of the rules. Basketball, football, and soccer are examples of sports that used this kind of ref.The word referee is also sometimes used to refer to a person who acts as a formal authority or arbitrator in some kind of decision, such as a legal case. Sometimes, the word refers to a person who’s responsible for reviewing scientific or academic papers or grant proposals. Referee can also be used in a figurative way to refer to someone who has to enforce the rules in some situation, as in I spent the afternoon playing referee to several toddlers.Ref can be used as a shortened form of referee in these contexts, but it’s much less common than its use in sports.Sometimes, the word is used as an informal way of addressing a referee, as in “Hey, Ref, good call!” said no one ever.  Like referee, ref can be used as a verb meaning to act as a referee, as in I signed up to ref my daughter’s soccer games. Example: I’ve never understood why players argue with refs—have you ever seen one reverse their call?
