laicolassë

masculine name. Green-foliage

The Quenya name of Legolas, a compound of laica “green” and olassë “foliage” (PE17/56).

Conceptual Development: In the much earlier Lost Tales, ᴱQ. Laiqalasse was given as the Qenya equivalent of the similarly named G. Legolas (LT2/217), though this was a completely different character, unrelated to the Legolas who appeared in The Lord of the Rings.
