phonetics

Etymology

It is formed from English phonetic + -ics.^[2][3][4] The adjective is from New Latin phoneticus, used in 1797 by Zoëga,^[2][3] from Ancient Greek φωνητικός (phōnētikós, “vocal, relating to speech”),^[2][3][4] from φωνητός (phōnētós, “to be spoken”),^[2][3] from φωνεῖν (phōneîn, “to produce a sound, to speak”),^[2][3] from φωνή (phōnḗ, “sound, voice”),^[2][3] from Proto-Indo-European *bha- (“to speak, tell, say”).^[3] The OED compares Italian fonetica, recorded in 1834.^[2]

Earliest recorded meaning

The study and classification of speech sounds: 1841, in R. G. Latham's The English Language.^[2][3] Merriam-Webster dates the word to 1836,^[5] and Dictionary.com gives 1835–45.^[4]

Semantic evolution

English already had phonology when the noun appeared, and the OED compares it.^[2] The adjective had been used since 1802 of written characters that stand for sounds rather than ideas,^[2] and its sense "relating to the human voice as used in speech" is dated by 1861 by Etymonline.^[3] Besides the science itself, Merriam-Webster records its practical application to learning and speaking languages, and the system of speech sounds of a given language.^[5]

It is plural in form but takes a singular verb.^[6][7] Collins treats it as the study of speech sounds as such, which can be applied to language study but strictly leaves out linguistic considerations, and contrasts it with phonology.^[6]
