From oui via dialectal variants; also possibly from oyez.
Before becoming an informal synonym of oui, the word was exclamatory. According to Auguste Scheler, it could be linked to Indo-European roots: οὐαί (ouaí) in Greek, vae in Latin, uau in Portuguese, wow in English, wau in German, guau in Spanish or vai in Romanian.
