Wat

Wat is an English given name originating as a medieval short form of Walter, which itself derives from the Old High German name Waldhar, composed of the elements wald, meaning rule or power, and hari, meaning army. The name was common in medieval England and is famously associated with Wat Tyler, the leader of the English Peasants' Revolt of 1381. The full form Walter remains widely used across Europe in various spellings, including Walther in German and Gautier in French.
