Quenya was the J.R.R. Tolkien language especially inspired by Finnish.
Tolkien developed Quenya as an Elvish language with a sound and grammatical structure influenced strongly by Finnish. He also drew on Latin and Greek, while creating an original vocabulary and history for the language within the mythology of Arda.
In Tolkien’s fictional history, Quenya was associated with the High Elves and was connected to the ancient cultural traditions of Valinor. Its prestige and ceremonial use distinguish it from Sindarin, another major Elvish language that appears more often in everyday dialogue in The Lord of the Rings.
The languages were not merely word lists. Tolkien constructed their phonology, grammar, vocabulary, and historical relationships, treating language creation as a central part of world-building. His professional work as a philologist helped shape this unusually detailed approach to invented languages.
