J.R.R. Tolkien gave the Elvish language used by many Noldor the name Quenya.
Quenya is one of Tolkien’s most developed constructed languages. In his mythology, it originated among the Elves of Valinor and was associated especially with the Noldor, a people who later returned to Middle-earth. Tolkien modeled parts of its sound and structure on languages including Finnish, Latin, and Greek, while creating its own grammar and vocabulary.
Within the fictional history, Quenya became a formal, literary, and ceremonial language in Middle-earth rather than the everyday speech of most Elves. Sindarin generally served as the more widely spoken Elvish language there. This distinction is why characters may use different Elvish terms depending on their culture and location.
Quenya is sometimes casually called “the Elvish language,” but Tolkien created several Elvish languages and dialects. Quenya is therefore a specific language, not a universal label for every form of Elvish speech in his legendarium.
