Meaning of Louis

Root meaning "famous warrior"

Louis is the French form of the Old German Chlodovech / Ludovicus: hlud ('famous') + wig ('warrior, battle'). The same root gives Ludwig (German), Lewis (English) and Luigi (Italian). Eighteen French kings bore the name Louis, cementing it as the quintessential French royal name. The English pronunciation differs markedly from the French — LOO-ee vs. LOO-is.

How to pronounce Louis

The s is silent in the French and most English pronunciations (LOO-ee). Lewis/Lewis is the anglicised spelling with a pronounced final s.
