"interpretive," 1670s, from Latinized form of Greek hermeneutikos "of or for interpreting," from hermeneutes "interpreter," from hermeneuein "to interpret (foreign languages); interpret into words, give utterance to," a word of unknown origin (formerly considered ultimately a derivative of Hermes, as the tutelary divinity of speech, writing, and eloquence).
in the names of sciences or disciplines (acoustics, aerobics, economics, etc.), a 16c. revival of the classical custom of using the neuter plural of adjectives with Greek -ikos "pertaining to" (see -ic) to mean "matters relevant to" and also as the titles of treatises about them. Subject matters that acquired their English names before c. 1500, however, tend to be singular in form (arithmetic, logic, magic, music, rhetoric). The grammatical number of words in -ics (mathematics is/mathematics are) is a confused question.
