In Grey-elvish or Sindarin the Dwarves are called Naugrim ("Stunted People"), Gonnhirrim ("Stone-lords"), and Dornhoth ("Thrawn Folk"), and Hadhodrim. In Quenya they are the Casári. The Dwarves call themselves Khazâd in their own language, Khuzdul. Khuzdul is created for them by Aulë, rather than being descended from an Elvish language, as most of the languages of Men are. They write it using Cirth runes, a writing system originally created by Elves in Beleriand to write Sindarin, and later more fully developed by Daeron, an Elf of Doriath. The Cirth runes are adapted by Dwarves for writing Khuzdul. The Dwarves keep their language secret and do not normally teach it to others, so they learn both Quenya and Sindarin to communicate with the Elves, especially the Noldor and Sindar. By the Third Age the Dwarves are estranged from the Elves and no longer routinely learn their language. Instead, they mostly use the Westron or Common Speech, a Mannish tongue, in communicating with other races.
