Tinúviel (S, pron. [tiˈnuːvjel]) is a Sindarin poetic term, though not a literal name, for the 'Nightingale'. This name was first given to Lúthien of Doriath by Beren when he first saw her dancing in the forest.
The word derives from Primitive Quendian tindômiselde. Literally it means "Daughter of Twilight".
It can be analyzed as tinnu(w) + sell.
