- another term for egotism.
late 18th century: from French égoïsme and modern Latin egoismus, from Latin ego 'I'
The words egoism and egotism are frequently confused, as though interchangeable, but there are distinctions worth noting. Both words derive from Latin ego (‘I’), the first-person singular pronoun. Egotism, the more commonly used term, denotes an excessive sense of self-importance, too-frequent use of the word ‘I,’ and general arrogance and boastfulness. Egoism, a more subtle term, is perhaps best left to ethicists, for whom it denotes a view or theory of moral behavior in which self-interest is the root of moral conduct. An egoist, then, might devote considerable attention to introspection, but could be modest about it, whereas an egotist would have an exaggerated sense of the importance of his or her self-analysis, and would have to tell everyone.
