The poem beginning “Namárië” in J.R.R. Tolkien’s works is written in Quenya.
Quenya is one of Tolkien’s major constructed languages, associated especially with the Elves known as the Eldar. Its name comes from a word meaning “speech” or “language” in the language itself. Tolkien developed its vocabulary, sound system, and grammar over many years, drawing inspiration from languages including Finnish and Latin.
“Namárië,” also called Galadriel’s Lament, appears in The Fellowship of the Ring. Galadriel sings it as the members of the Fellowship depart from Lothlórien. The poem expresses longing for the lands across the sea and is one of the longest examples of Tolkien’s invented languages in the novel.
Sindarin is another major Elvish language and is more commonly used in spoken dialogue in Middle-earth. Adûnaic is associated with Númenor, while Khuzdul is the secret language of the Dwarves. Those languages are distinct from Quenya.
