What is the meaning of the name Lou ?

The baby name Lou is a Unisex name , 1 syllables long and is pronounced /luː/ (LOO).

Lou is in Origin.

Lou is a compact, unisex diminutive used in French and English for several longer names. Most commonly it shortens Louis, Louise, and Louisa, descendants of Old High German Hludwig (hlud “famous” + wig “war”), yielding the sense “famous warrior” or “renowned in battle.” It also serves as a pet form of Lucille, Lucia, and Lucinda, from Latin lux “light,” giving Lou a second, luminous meaning. As a standalone given name, Lou is pronounced LOO in both languages.

In the Anglophone world, Lou appears on records from the 19th century and peaked in the early–mid 20th century for men through figures like Lou Gehrig and Lou Reed, while in modern France it has surged as a chic feminine choice since the 1990s. Related forms and nicknames include Louis, Lewis, Louise, Louisa, Lucille, Lucia, Lucinda, Louie, Lew, Lulu, Lula, and Loulou; compound forms such as Mary Lou are also common.
