A more thorough explanation:

Definition: Demeanor refers to a person's outward appearance or behavior, including their facial expressions, tone of voice, gestures, and how they respond to questions.

Example: During a job interview, the interviewer may pay attention to the candidate's demeanor to determine if they are confident, friendly, and professional. If the candidate avoids eye contact, speaks softly, and fidgets, their demeanor may suggest that they lack confidence or are nervous.

Example: In a courtroom, the jury may observe the demeanor of a witness to determine if they are telling the truth. If the witness avoids eye contact, speaks hesitantly, and appears nervous, their demeanor may suggest that they are not being truthful.

The examples illustrate how demeanor can provide insight into a person's emotions, personality, and credibility. By paying attention to someone's demeanor, we can better understand their intentions and feelings.
