Khuzdul

Khuzdul is the fictional language of the Dwarves in J. R. R. Tolkien's Middle-earth. It appears to be structured, like Semitic, around triconsonantal roots: kh-z-d, b-n-d, z-g-l. Not much is known of the language, as the Dwarves kept it to themselves, except for their battle-cry: Baruk Khazâd! Khazâd ai-menu! meaning Axes of the Dwarves! The Dwarves are upon you!

Among the languages of Middle-earth, Khuzdul is unique in belonging to a separate language phylum, not related to the languages of Elves or Men.
