Aulëan
From Tolkien Gateway
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 was named from the Dwarvish tradition that it had been devised by Aulë the Smith, the Vala who created the Dwarves.
This concept was later dropped.
