What Does Demeanor Mean?

“Demeanor” is a noun that means someone’s behavior towards other people. For instance, someone’s demeanor will show happiness, sadness, terror, or excitement. This word goes way deeper than just talking about a person’s actions, though; it can also show your thoughts or true feelings.
So, how about its origin? Well, demeanor originally comes from the Latin word “dimari” which means “to threaten” or “to make someone move.” That led to words about guiding people, leading animals, and general behavior. Eventually came the Middle English word “demean.” Now, the modern demeanor meaning combines behavior and attitude.
You can use demeanor in sentences like these:
- He always got detention after school for his bad demeanor in class.
- I try to show a positive demeanor at work, even when the customers are rude.
- Her grandmother’s judgmental demeanor made it clear she didn’t enjoy the restaurant.
- Jason’s excited demeanor was obvious after his team won the football game.
- He gave a warm demeanor when he met his future mother in law.
- His demeanor suggest that he is guilty of inappropriate conduct.

When and How to Use Demeanor?
Demeanor can be the subject of a sentence because it’s a noun. This means you can use the word when you’re talking about someone’s behavior or attitude. Here are a couple of examples:

- Does the waiter’s enthusiastic demeanor seem fake to you?
A demeanor can also cause actions, like in these sentences:
- Her rude demeanor hurt my feelings.
- Mike’s happy demeanor always made his friends smile.
But demeanor isn’t a verb, so you can’t use it to describe someone’s actions. “Demean” is a verb, and it sounds like demeanor, but they mean very different things.
You can use demeanor anytime someone’s responses don’t fit the situation. If someone is trying to be polite but they’re actually furious, using “demeanor” tells people it’s all a mask. Again, this also works when someone acts happy, but you can tell they feel sad.
Want more examples? Demeanor is a good word choice if someone is acting in these ways:
- Passive-aggressive
- Two-faced
- Shady
- Snide
- Fake
- Catty
- Underhanded
- Overly polite
- Artificial
Finally, demeanor can also be a positive word! It simply means that you can tell someone’s attitude from their actions. For example, you can have a happy, joyful, professional, or excited demeanor as long as your behavior fits your feelings.
Demeanor or Demeanor: What’s the Correct Spelling?
Do you know how to spell demeanor? Maybe you’ve also seen this word written as “demeanour,” with the letter U in between the letters O and R. If you think that this is a misspelling, you’re wrong because either demeanor or demeanour is correct.
“Demeanor” is the correct spelling in American English. But British/UK English spells it as “demeanour” with an extra u.
How do you know which spelling to use? Just stick with whatever version of English you normally use. In short, if you are in the United States, use the American spelling (demeanor). If you are in the United Kingdom or writing for a British audience, opt for “demeanour.” Remember, consistency is also important in grammar.
Final Thoughts
In recap, the demeanor meaning is your outward behavior. And remember, someone’s demeanor can reveal or mask their true emotions. If this noun sounds too formal, try its synonyms like attitude, mask, or act.
