Lill is a name of Norwegian origin, derived from the Old Norse word 'hildr', which means 'battle'. It is often considered a female name, but it can also be used for males. In Scandinavia, Lill has been traditionally popular as a given name, although its usage has declined in recent decades. The name has not gained significant international recognition, remaining predominantly Scandinavian.
