Sindarin is an artificial language developed by J. R. R. Tolkien. In Tolkien's mythos, it was the most spoken Elvish language ever. It was the language of the Sindar, those Teleri which had been left behind on the Great March of the Elves. When the Noldor came back to Middle-earth, they adopted the Sindarin language, although they believed their native Quenya more beautiful. Before the downfall, most of the Men of Númenor also spoke the language. Knowledge of it was kept in the Númenorean realm in exile Gondor, especially amongst the learned.
