An adjective in The Etymologies of the 1930s glossed “naked” and derived from primitive ᴹ✶skelnā under the root ᴹ√SKEL (Ety/SKEL). This word was originally hall “naked” under an earlier but deleted form of the root ᴹ√SKAL (EtyAC/SKEL). The root ᴹ√SKEL was also the basis for the verb N. heltha- “to strip”, and its Quenya derivative ᴹQ. helda was at one point was glossed “stripped bare” (Ety/SKAL¹), so the word hell seems to mean “naked” in the sense “✱stripped (of clothing or other covering)”.
Conceptual Development: There are a couple of earlier “naked” words in the Gnomish Lexicon of the 1910s that seems to be similarly derived. G. dautha “naked, stripped” was related to daf- “to strip, flay” (GL/29) and G. hulc “naked” (GL/49) is like the cognate of ᴱQ. hulqa “naked” under the early root ᴱ√HULU “strip” (QL/41). In later writings, some “naked” words were derived from √PAR “peel” instead (PE17/86, 171).

lhumren
adjective. shady
lhumren
noun. shady
A word appearing as N. lhumren “shady” in The Etymologies of the 1930s, an adjective form of N. lhum “shade” (Ety/LUM).
Conceptual Development: The earliest iteration of this word was G. lómin “shady, shadowy, gloomy; gloom(iness)” from the Gnomish Lexicon of the 1910s, the adjective form of G. lôm “gloom, shade” (GL/54). A similar word G. lumbrin or lumba “overcast” was an adjective based on G. lum “a cloud” (GL/55).
Neo-Sindarin: Since the root √LUM “shadow, darkness” survived in later writings (PE17/168), I think N. lhumren “shady” can be salvaged, though if adapted to Neo-Sindarin it would need to become ᴺS. lumren as suggested in HSD (HSD). Given the later use of Q. lumbo for “(dark) cloud”, I think the sense “overcast” from Gnomish lumbrin can be salvaged as well.
A word in The Etymologies of the 1930s glossed “exalted, high” derived from primitive ᴹ✶khalnā “noble, exalted” based on the root ᴹ√KHAL “uplift” (Ety/KHAL²). It was an element in more emphatic N. orchal (or orchel) “superior, lofty, eminent” (EtyAC/KHAL²).
Neo-Sindarin: Based on later more prosaic translations like S. orchal “tall” (WJ/305) and Q. halla “tall” (LotR/1123), I would assume hall can meaning “of high position” both physically and socially for purposes of Neo-Sindarin, not unlike English “high”.
