The demeanor meaning is a person’s outward behavior, manner, or way of appearing to others.
It describes how someone seems to behave, especially through their attitude, facial expressions, body language, and general manner.
For example, if someone remains calm and polite during a difficult situation, you might say they have a calm demeanor.
If someone looks angry or unfriendly, they may have a hostile demeanor.
The word is often used when describing how a person presents themselves rather than what they are secretly feeling.
Demeanor is common in everyday English, professional writing, news reports, and descriptions of people.
Understanding this word can help you describe someone’s behavior more precisely than simply saying they are “nice,” “angry,” or “quiet.”
