Epistemology
The word "epistemology" is derived from the ancient Greek "epistēmē" meaning "knowledge" and the suffix "-logy", meaning "logical discourse" (derived from the Greek word "logos" meaning "discourse"). It is analogue to the German "Wissenschaftslehre" (literally, theory of science) which was introduced by philosophers Johann Fichte and Bernard Bolzano in the late 18th century. The word first appeared in English in 1847 as a translation of the German in New York's "Eclectic Magazine" review of a philosophical novel by German author Jean Paul:
Encyclopedia
The word "encyclopedia" comes from the Koine Greek , transliterated "enkyklios paideia", meaning "general education" from "enkyklios" (ἐγκύκλιος), meaning "circular, recurrent, required regularly, general" and "paideia" (παιδεία), meaning "education, rearing of a child"; together, the phrase literally translates as "complete instruction" or "complete knowledge". However, the two separate words were reduced to a single word due to a scribal error by copyists of a Latin manuscript edition of Quintillian in 1470. The copyists took this phrase to be a single Greek word, "enkyklopaidia", with the same meaning, and this spurious Greek word became the New Latin word "encyclopaedia", which in turn came into English. Because of this compounded word, fifteenth century readers and since have often, and incorrectly, thought that the Roman authors Quintillian and Pliny described an ancient genre.
