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:
Etymologiae
Book X is a word-list of nouns and adjectives, together with supposed etymologies for them. For example, the letter 'D' begins with the word for master ("Dominus"), as he is the head of a household ("Domus"); the adjective docile ("docilis") is derived by Isidore from the verb for "to teach" ("docere"), because docile people are able to learn; and the word for abominable ("Nefarius") is explained as being not worth the grain called spelt ("Far").
