Episteme
"Episteme" is a philosophical term derived from the Ancient Greek word ἐπιστήμη "epistēmē", which can refer to knowledge, science or understanding, and which comes from the verb , meaning "to know, to understand, or to be acquainted with".
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.
