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