- Demeanor is a noun that refers to someone’s outward behaviour and appearance.
- Demeanor is spelled demeanour everywhere except the United States.
If you have ever had your professional demeanor criticized, you know that demeanor can be very important. Your demeanor affects how people perceive you. An unprofessional demeanor in a professional situation could get you fired, so you’d better learn what the word means.
Your demeanor is your outward behavior. It includes the way you stand, the way you talk, your facial expressions, and more. Someone with a friendly demeanor might smile a lot and look you in the eye while talking to you. Someone with an unfriendly demeanor might stand with their arms crossed and give you curt one-word answers to all your questions. The root of demeanor is the Latin word minari, which means to threaten and was used mostly to describe the sounds made by cattle herders. By the time the word reached Anglo-French, it meant “to conduct,” and it was in Middle English that it acquired the form “demenen” and the meaning “to conduct oneself.”
And that’s how the word is used today—one meaning of demean is still “to conduct oneself in a certain way,” even though the other meaning, “to insult,” is more common today. Adding the suffix -or to the demean gives us a noun and a synonym for conduct.
But conduct aside, are there any other words that mean the same thing as demeanor? The meaning of behavior overlaps a great deal with the meaning of demeanor. Bearing is another synonym, as are deportment and manner.
Demeanor vs. Demeanour
No harm done if you write demeanor with an extra U—demeanour. In fact, that’s the preferred spelling in every English-speaking country except the United States. So with or without the U, the spelling is correct.
That can’t be said for other demeanor spellings, like “demenor,” “deamenor,” or “demeaner.” Sorry, those version are wrong—you get to choose between demeanor and demeanour, and that’s it.
