ETYMOLOGY of acou-

greek

Component	Origin	Meaning
acou- / acous- / acu-	Greek ἀκούειν (akouein), from ἀκοή (akoē)	“hear,” “hearing,” “sound” — sensory combining form denoting auditory perception

The word entered English in the 1620s as acoustic (adjective), borrowed from French acoustique, from Latin acusticus, from Greek ἀκουστικός (akoustikos) — literally “pertaining to hearing.” The noun acoustics appeared in the 1700s, and acoumeter in the 1850s. The root akouein (“to hear”) connects acou- to the entire hearing and auditory roots: acoustic neuroma (acou- + stic + neuroma $\to$ tumor of the auditory nerve), acoumetry (acou- + -metry $\to$ measurement of hearing acuity), and acouphenia (acou- + phainesthai $\to$ phantom sound perception/tinnitus). The combining form acou- is productive in otolaryngology, audiology, and neurology: e.g., acouesthesia, acousticophobia, acousma, and acoumeter.
