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:
Pisco
This claim is disputed by Chilean linguist Mario Ferreccio Podesta, who supports the former Real Academia Española etymology according to which "pisco" was originally a word for a mud container. However, the Real Academia Española later supported Lenz's theory, and underlines the Quechua origin.
