History for encyclopedia

If you read an entire encyclopedia, you might learn something about nearly everything, and, suitably, the original sense of the word encyclopedia was “general education” or “education in all branches of knowledge.” Encyclopedia is formed from two Greek words, enkyklios, meaning “circular, recurrent, ordinary,” and paideia, “education.” Paideia is itself a derivative of pais, “child.”
