Origin & History of “vowel”
A vowel is etymologically a ‘vocal’ sound – that is, one made by vibrating the vocal chords. The word comes via Old French vouel from Latin vōcālis. this was short for littera vōcālis ‘vocal letter, letter that sounds’, sonus vōcālis ‘vocal sound’, etc. Vōcālis (source of English vocal) was derived from vōx ‘voice’ (source of English voice).
