A word for “dream” in Tolkien’s later writings, most notably as an element in Lórien “✱Dream Lands” (Let/308; PE17/80). In The Etymologies of the 1930s, however, ᴹQ. lóre was glossed “slumber” under the root {ᴹ√LOR >>} ᴹ√LOS “sleep” (Ety/LOS).
Neo-Quenya: I generally use √LOR for “sleep” and √OLOS for “dream” for purposes of Neo-Eldarin. As such, I would use lóre for both “slumber, ✱sleep” and “dream” for purposes of Neo-Quenya, likely a blending of primitive ✱lōre and ✱lōse. But I would use it more for a “(dreamful) sleep”, with olor as the proper word for “dream” or “vision”.
A word for “vapour, steam” in some 1957 notes, derived from the same root √PHAN that is the basis for Q. fanya “cloud” (NM/237).
