Etymology

It is inherited from Proto-Italic *swonos, inherited from Proto-Indo-European *swónh₂os, from the root *swenh₂- (“to sound”).[1][2] The verb sonō “to sound” is from the same root.[3][4]

Georges compares Sanskrit स्वन (svaná, “sound”).[5]

Earliest recorded meaning

It is found from Ennius onwards,[3][6] who writes “a harsh sound ran through the bronze” and “the sweet voice of Egeria answered him”.[4][7]

Semantic evolution

It meant a sound or noise, as Sisenna's Gauls advancing with great uproar and Cicero's flutes that give no sound.[4] It meant articulate sound, speech or utterance, as Ennius' Egeria, and the distinctive quality of a voice, pronunciation or accent, as Cicero's urban accent of Rome compared with the Attic.[4]

Cicero also used it of the highest and lowest musical notes.[5] Figuratively it meant tone or style.[1] In Medieval Latin it was the ringing of bells.[6] English sound came from it through Old French son in the late 13th century.[2]
