A verb appearing as G. lor- “sleep deep, dream” (GL/54), clearly based on the early root ᴱ√LORO “doze, slumber” (QL/56).
Neo-Quenya: I’d retain the verb ᴺS. lor- for purposes of Neo-Sindarin, but with the sense “sleep, slumber” only; for “dream” I’d use N. oltha- (Ety/ÓLOS). This neologism has likely been floating around for a while, but it was first suggested to me by Elaran.
A noun in the Gnomish Lexicon of the 1910s glossed “sleep, slumber” (GL/49), likely based on the early root {ᴱ√HUMU >>} ᴱ√FUMU “sleep” (QL/39).
