English encyclopedia Borrowed from New Latin encyclopēdīa, encyclopaedīa (“general education”), a univerbated form of Koine Greek ἐγκύκλιος παιδείᾱ (enkúklios paideíā, “education in the circle of arts and sciences”), from Ancient Greek ἐγκύκλιος (enkúklios, “circular”) + παιδείᾱ (paideíā, “childrearing; education”) (q.v.). Nearly all modern English usage of the word was influenced by the scope and format of the French Encyclopédie by Diderot et al. (see quotation).
