Entries linking to phonetics
phonetic adj.
1803, "representing vocal sounds," from Modern Latin phoneticus (Zoega, 1797), from Greek phōnētikos "vocal," from phōnētos "to be spoken, utterable," verbal adjective of phōnein "to speak clearly, utter," from phōnē "sound, voice," from PIE root *bha- (2) "to speak, tell, say" (see fame (n.)). Meaning "relating or pertaining to the human voice as used in speech" is by 1861. Related: Phonetical.
-ics
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.
