Synonyms: arrogant, haughty, disdainful, supercilious
These adjectives mean characterized by an inflated ego and disdain for what one considers inferior. One who is arrogant is overbearingly proud and demands excessive power or consideration: an arrogant and pompous professor, unpopular with students and colleagues alike. Haughty suggests superiority, as by reason of high status: “Her laugh was satirical, and so was the habitual expression of her arched and haughty lip” (Charlotte Brontë).
Disdainful emphasizes scorn or contempt: “Nor [let] grandeur hear with a disdainful smile, / The short and simple annals of the poor” (Thomas Gray).
Supercilious implies haughty disdain and aloofness: “Failure would confirm the critics who called him supercilious for following his own methods and not theirs” (Neal Bascomb).
