What does Lou mean?
/luː/1 syllable

Lou is a short form of Louis or Louise, names that trace back to the Old Germanic Hludwig, combining elements meaning "famous" and "warrior" or "battle." The name spread widely through French royalty named Louis before becoming an independent nickname.

Lou is easy and unpretentious, the kind of name that suits a companion with a plainspoken, steady charm rather than anything showy.
