- proper n. A constructed language based on Welsh.
Developed by J. R. R. Tolkien and mainly spoken by the Elves in his fantasy works. The word Sindarin itself is not of Sindarin origin: it is a Quenya term for the language that was probably referred to as Edhellen in the language. It is the genitive form of Sindar, the name of the people who spoke it. (Wiktionary)
