egomaniacal adjective

Did you know?

Ego is Latin for "I", and in English ego usually means "sense of self-worth". Most people's egos stay at a healthy level, but some become exaggerated. Egomaniacs may display a grandiose sense of self-importance, with fantasies about their own brilliance or beauty, intense envy of others, a lack of sympathy, and a need to be adored or feared. But, like megalomaniac, the word egomaniac is thrown around by lots of people who don't mean much more by it than blowhard or know-it-all.
