From Tolkien Gateway

Aldudénië is a poem lamenting the death of the Two Trees, composed by Elemmírë of the Vanyar, soon after the event. It was famous to all the Eldar.[1]

Etymology[edit | edit source]

Aldudénie is said to mean "lament of the Two Trees" and contains aldu, the dual of alda "tree".[2]

The other element *dénie which obviously means "lament", is of problematic etymology since the intermedial "d" does not exist in Quenya (only the "ld" "nd" and "rd" are present).

Another similar Quenya word for lament is nainië from Root NAY.
