conceited
UK: kənˈsiːtɪd | US: kənˈsiːtɪd
adj. excessively proud of oneself; vain
adj. having an exaggerated sense of one's importance or abilities
The word "conceited" derives from "conceit," which originally meant "idea" or "notion" (from Latin conceptum, via Old French conceit). Over time, "conceit" evolved to mean "excessive pride in oneself," likely influenced by the idea of being overly preoccupied with one's own thoughts or image. The suffix "-ed" transforms the noun into an adjective, emphasizing the state of being vain or self-important.
