What fictional language did J.R.R. Tolkien call Quenya?

J.R.R. Tolkien called Quenya an Elvish language.

Quenya is one of the major languages Tolkien created for the Elves of his legendarium. It is associated especially with the Noldor and with the high cultural traditions of the Elves. Tolkien developed its sound and grammar partly from his interest in historical languages, particularly Finnish.

Quenya is not the same as Sindarin, another major Elvish language in Tolkien’s fiction. Sindarin became the everyday Elvish speech of many characters in Middle-earth, while Quenya often has a formal, ancient, or ceremonial role. Tolkien’s language invention was central to his world-building: he developed histories and peoples partly through the relationships between their languages.
