The name Wy comes from the Latin vicus – meaning "village" or cluster of houses (as opposed to a villa, an isolated farm and master's residence).
The full name Wy-dit-Joli-Village ("Wy-called-Pretty-Village") is said to have arisen from an incident in which King Henry IV of France, hunting in the area and enquiring what the settlement was called, exclaimed Ah! Quel joli village! : "Oh, what a pretty village!"
