belittle

This term describes a psychological tactic of devaluation, often used to undermine a person's confidence or status. It carries a strong negative connotation of arrogance or cruelty, suggesting a deliberate attempt to diminish the perceived worth of another's efforts or character.

In professional or social hierarchies, it differs from simple criticism by focusing on the insignificance of the subject rather than the flaws of the work. It is frequently associated with narcissism or insecurity in the speaker, who seeks to elevate themselves by pushing others down.
