What does hatter mean?
Hatter is a noun whose traditional meaning is a person who makes or sells hats. The occupational sense comes from the modern English word hat and the suffix -er, which identifies the person doing or dealing with something. Although “hatter” may sound old-fashioned when used literally, it remains familiar through the expression “mad as a hatter,” meaning extremely eccentric, irrational, or seemingly crazy. The precise origin of that idiom is uncertain, but it has been established in ordinary English for well over a century and is now used mainly for humorous or exaggerated effect. The phrase does not ordinarily imply a medical condition or provide a literal description of a hat maker's behavior. In general writing, “hatter” is more likely to appear in the idiom than as a standalone occupational label. It is useful because it preserves the history of an old trade while also participating in one of English's most recognizable expressions for unconventional behavior.
