“Quenya?” repeated Bilbo. “It’s a language—quite a formal Elvish language that is, I am told, spoken by few. It’s the language of the High Elves, those who beheld the Powers in the time of the Trees before the Noldor returned to Middle Earth in pursuit of the Marrer after he destroyed the Trees and stole the Silmarils. The High King of the Elves of Middle Earth, learning these had slain their mutual kindred in order to sail here, forbade that it be spoken openly, and thusly few use it. But it’s not forgotten.”
Frodo pondered this information consideringly.
