Aulëan
Within
J.R.R. Tolkien's conception of the
languages of Middle-earth as expounded in the
Lhammas,
Aulëan is the language phylum of
Khuzdul, the language of the
Dwarves. It is there contrasted with
Oromëan, the language phylum of the Elvish languages such as
Quenya and
Sindarin.
Aulëan is so named because its ancestral language supposedly derives from the speech of Aulë the Smith, the Vala who created the Dwarves.
