Lou

Famous warrior, through Louis or Louise.

Lou is a short form of Louis or Louise and is used for women and men in French and English. Through those fuller forms, it belongs to the Germanic Ludwig family, whose elements mean “fame” and “battle”. The familiar interpretation “famous warrior” comes from that ancestry. In French /lu/ and English /luː/, Lou has one syllable. The l leads straight into a rounded vowel, with no closing consonant to interrupt it. That flowing sound can feel friendly and relaxed, while the written ou gives Lou a different look from Lu. Its appeal lies in a clear, open sound that is easy to linger on.

Etymology: Lou is a short form of Louis or Louise. This name family goes back to Germanic elements meaning “fame” and “battle”.
