Quenya is the Tolkien-created Elvish language based largely on Finnish.
Tolkien developed Quenya as one of the major languages of the Elves. Its sound system and grammar were strongly influenced by Finnish, while its vocabulary and history were shaped by Tolkien’s broader study of languages, including Welsh, Latin, Greek, and Germanic languages.
Within the fictional history of Middle-earth, Quenya was associated especially with the High Elves and the ancient realm of Valinor. It remained a prestigious, literary, and ceremonial language even after Sindarin became more widely spoken among many Elves in Middle-earth.
Quenya is often confused with Sindarin because both are prominent Elvish languages in The Lord of the Rings. Sindarin was influenced particularly by Welsh, whereas Quenya’s most frequently noted real-world linguistic influence is Finnish. Tolkien created both languages with internal histories and relationships rather than as simple lists of translated words.
