Which term refers to showing arrogance and disdain towards others?

The term that refers to showing arrogance and disdain towards others is "supercilious." This word characterizes a person who behaves or looks as though they think they are superior to others. Such individuals often exhibit a condescending attitude and may dismiss others as unworthy or inferior. In social contexts, being supercilious can manifest through actions, body language, and tone that suggest a lack of respect or regard for those considered beneath them in status or ability.

Understanding the other terms helps contextualize why "supercilious" is the most fitting choice. "Tenuous" relates to something that is weak or insubstantial, which does not convey an attitude of arrogance. "Superfluous" means something excessive or unnecessary, lacking the connotation of disdainful superiority. Finally, "stymie" refers to the act of obstructing or hindering someone, which is contrary to the implication of having an arrogant demeanor. Thus, "supercilious" accurately captures the essence of showing disdain and arrogance towards others.
