superciliously

This term describes a specific type of arrogance characterized by a sense of haughtiness and a visible display of disdain. It often implies a physical manifestation of superiority, such as a raised eyebrow or a cold, dismissive gaze, suggesting that the person views others as inferior or unworthy of respect.

In terms of register, it is a sophisticated, formal word. While "arrogantly" is a general term for overbearing pride, "superciliously" specifically captures the nuance of looking down on someone from a perceived higher social or intellectual station. It is rarely used in casual conversation and is more common in literary descriptions or formal critiques of behavior.
