英文词源

ego

ego: [19] Ego is Latin for ‘I’ (and comes in fact from the same Indo-European base as produced English I). English originally acquired it in the early 19th century as a philosophical term for the ‘conscious self’, and the more familiar modern uses – ‘self-esteem’, or more derogatorily ‘selfimportance’, and the psychologist’s term (taken up by Freud) for the ‘conscious self’ – date from the end of the century.

Derivatives include egoism [18], borrowed from French égoïsme, and egotism [18], perhaps deliberately coined with the t to distinguish it from egoism. And the acquisitions do not end there: alter ego, literally ‘other I, second self’, was borrowed in the 16th century, and the Freudian term superego, ‘beyond I’, entered the language in the 1920s.
