A root in The Etymologies of the 1930s glossed “glass” with derivatives in both Quenya and Noldorin with the same meaning: ᴹQ. hyelle and N. hele (Ety/KHYEL(ES)). After Tolkien changed Noldorin to Sindarin, he decided that “There was no common Eldarin word for glass”, and that the Sindarin word S. heledh was derived from Khuzdul kheled (PE17/37). Thus the root ᴹ√KHYEL(ES) was abandoned.

root. day
A root in The Etymologies of the 1930s glossed “day” with various derivatives like ᴹQ. are, N. aur “day” and ᴹQ. arin “morning” (Ety/AR¹). In Tolkien’s later writings, the Quenya word for “day” became aurë (RC/727; S/190), and in 1957 Quenya Notes he devised a new etymology for these day-words from the root √UR “heat” as in ✶auri “heat, period of sun” (PE17/148). That opens the question whether the various 1930s Quenya “morning” words from ᴹ√AR remain valid, but many Neo-Quenya writers (including me) retain them since there aren’t really any good alternatives. They might be salvageable as derivatives of the later root √AS “warmth” (so that “day” = “hot” and “morning” = “warm”).

us
root. [unglossed]
A root in The Etymologies of the 1930s with no glosses or derivatives and no clear function (EtyAC/US).
A (Noldorin-only) root in The Etymologies of the 1930s, a strengthened form of the root ᴹ√LAM which was the basis of general sound words (Ety/GLAM). The derivatives of ᴹ√GLAM include N. glamm “shouting, confused noise” and N. glavra- “babble” but also N. glamor “echo” and N. glamren “echoing”, the last of these seen in N. Dorlamren, the pure Noldorin form of N. Dor-lómen “Land of Echoes”, which incorporates the Ilkorin word lómen “echoing” (LR/249; Ety/LAM).
The word S. glam “din, uproar, the confused yelling and bellowing of beasts” reappeared in the Quendi and Eldar essay written in 1959-60, where it was an element (as it was earlier) in the collective name for orcs: S. Glamhoth “Din-horde” (WJ/391). This strongly indicates that the “confused sounds” aspect of this root survived into Tolkien’s later conception of the language. However, the “echo” portion seemed to have been transferred to the unstrengthened form of this root √LAM as with (West) Sindarin loven “echoing” vs. North Sindarin lómin, which remained an element in Dor-lómin “Land of Echoes”, albeit reconceived of as a North Sindarin name (PE17/133).
