"Variant of Liliane"
The name Lilou is commonly a female name from the "Latin" origin.
Lilou is a French feminine given name. It is a diminutive formed with the familiar French ending -ou, the same pattern seen in Loulou from Louise, and it is used as a short form of Liliane. It has no separate meaning of its own beyond that of the name it shortens.
Liliane means "Noble. The Hebrew form of Elizabeth, Holy and sacred to God.".
The pronunciation of Lilou is LEE-loo.
