From Proto-Italic *swonos, from Proto-Indo-European *swónh₂os, from the root *swenh₂- (“to sound”). The lack of the sound change *mo- > *ma- in open syllabels is potentially because the syllable was closed before the word-medial laryngeal. De Vaan alternatively reconstructs earlier *swenos, though he does consider it possible that the term was deverbal form sonō, sonāre. Cognate with Proto-Germanic *swanaz.
