Quenya is the fictional language J.R.R. Tolkien created that is also called High-elven.
Quenya is one of Tolkien’s Elvish languages and was associated especially with the High Elves. Tolkien developed it with substantial attention to sound patterns, grammar, vocabulary, and historical change, drawing inspiration from languages including Finnish and Latin.
Sindarin is another major Elvish language, but it is distinct from Quenya and became the everyday language of many Elves in Middle-earth. This distinction is a common source of confusion because both languages appear in Tolkien’s names, poetry, and songs.
Tolkien’s languages were not merely collections of invented words. He often built fictional histories for them, allowing related languages to evolve over time in a way resembling real historical linguistics.
