(Quenya for "Lament for the Two Trees")
A poem lamenting the death of the Two Trees, composed by Elemmírë(Elf) of the Vanyar, soon after the event. Famous to all the Eldar but not recorded.
The name is problemous for the Tolkien scholars, because the sound "d" doesn't exist in Quenya. It might be some idiom of the Vanyarin.
