Some have rejected the conclusion on the grounds that these entries were written before LotR was begun and therefore may not apply to it. It is thus significant that the element 'las' retained both its meanings, as is shown by examples in LotR itself, such as Legolas ('Green leaf') (TT, 106, 154), 'lassi' (== "leaves") in Galadriel's Lament (FR, 394), and Amon Lhaw (Hill of Hearing) (FR, 410).

- *lasse 'leaf': Q lasse, N lhass; Q lasselanta 'leaf-fall, autumn', N lhasbelin (*lassekwelene), cf. Q Narquelion [ KWEL ]. Lhasgalen 'Greenleaf' (Gnome name of Laurelin). (Some think this is related to the next and *lasse 'ear'. The Quendian ears were more pointed and leaf-shaped than [human].)
