What is a characteristic of someone who is supercilious?

A supercilious person is characterized by an attitude of arrogance and condescension, often looking down on others with disdain. This behavior typically manifests in dismissiveness or a belief in their own superiority, leading them to treat others as inferior. The term itself is derived from the Latin word "superciliosus," which means haughty or disdainful.

Both the disdainful attitude and the display of arrogance are intrinsic to someone who is supercilious, making the combined option that encompasses both traits the most accurate response. Thus, an individual who embodies superciliousness will inevitably demonstrate both utter disdain and a sense of arrogance in their interactions.
