What does swellhead mean?
Swellhead is an informal noun for a conceited or self-important person, especially one who is puffed up with pride or constantly boasts about their abilities. It is more disparaging than simply describing someone as confident: the word implies that the person’s sense of importance is excessive and may not be matched by real achievement. A “swellhead” may also be portrayed as vain, boastful, or unwilling to listen to anyone else. The term is comparatively old-fashioned and now sounds somewhat literary, humorous, or deliberately insulting. It can be used in conversation, fiction, and commentary, but it is not the neutral term for an ambitious or successful person. The related adjective “swell-headed” is sometimes used to describe the same quality. In modern usage, “arrogant,” “self-important,” and “boastful” are generally more common and more flexible alternatives.
