Yanns

Yanns is a variant of Yann, which itself is a Breton form of John. The name John originates from the Hebrew name Yochanan, meaning 'Yahweh is gracious' or 'God is gracious'. The name spread throughout Europe with the advent of Christianity, becoming one of the most perennially popular names due to its association with John the Baptist and John the Apostle.

In Brittany, a region in northwestern France with a distinct Celtic heritage, the name evolved into Yann. The 's' at the end of Yanns is likely a diminutive or a regional suffix, common in some European languages to create variations or patronymic forms, though in this specific case it often functions as a simple phonetic or stylistic alteration.
