J.R.R. Tolkien created Quenya for the Elves of Valinor and used it in names such as Galadriel.
Quenya is one of Tolkien’s best-developed Elvish languages. It is associated especially with the high Elves, including the Ñoldor, and is influenced in sound and structure by languages such as Finnish, Latin, and Greek. Tolkien continued refining it throughout his life.
Galadriel’s name has a Quenya form, Alatáriel, although “Galadriel” itself belongs to Tolkien’s broader linguistic history and is associated with Sindarin usage. This distinction is why Elvish names can appear in different forms depending on context.
Quenya is often called an Elvish or “High-elven” language, while Sindarin is the more commonly spoken Elvish language in much of Middle-earth during The Lord of the Rings. Tolkien’s languages were not merely decorative vocabulary lists: he built grammars, sound changes, writing systems, and imagined histories for them.
