Erwan (Breton pronunciation: [ˈeʁwãn]) is a masculine Breton given name, sometimes spelled Erwann.
Its francization is the French given name Yves.
It might thus be formed of Proto-Brythonic words eu- "well, good" and *don "talent, natural gift, ability" (compare Welsh dawn and Irish dán), or derived from Gaulish name Esugenos.
[1][2] Sometimes allegedly supposed to come from the Breton word aerouant "dragon" because of homophony in Modern Breton.
