How to say it

LOU · is

/ˈlu.i/

What it means

French form of Germanic Hludwig (hlud 'fame' + wig 'warrior'). Eighteen kings of France took the name, including Louis XIV the Sun King. The English Lewis is the same root.

Louis is the French form of the Germanic Hludwig (hlud 'famous' + wig 'warrior'). Eighteen kings of France were named Louis; the line includes Louis IX (Saint Louis), Louis XIV (the Sun King, 17th century), and Louis XVI (executed in the French Revolution). The Anglicized Lewis became standard in English. As a US given name Louis was strong in the 19th and early 20th centuries (Louis Armstrong, Louis Pasteur), faded mid-century, and is climbing again. The standard French pronunciation drops the final S (LOO-ee); American English sometimes sounds it (LOU-iss). Louis Tomlinson (One Direction) gave it a 2010s anchor. Lou is the universal short.
