    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 use of the word influenced by the scope and format of Diderot & al.'s French Encyclopédie.

    • The spelling encyclopedia is standard in American English, common in Canadian English, accepted in Australian and International English, and also very common in British English although nonstandard. Oxford spelling prefers the etymologized form encyclopaedia, which restores the αι diphthong in Ancient Greek παιδεία. The variant with the æ ligature still appears in the titles of some encyclopaedic works, but it is otherwise archaic in ordinary usage.
