A word in The Etymologies of the 1930s appearing as N. lhae “great number” derived from primitive ᴹ✶lai- which was an a-fortified form of the root ᴹ√LI “many” (EtyAC/LI).
Neo-Sindarin: Many Neo-Sindarin writers adapt this word as ᴺS. lae “great number” for purposes of Neo-Sindarin as suggested in HSD (HSD), since the unvoicing of initial l to lh was a feature of Noldorin of the 1930s but not Sindarin of the 1950s and 60s.
Conceptual Development: Early Noldorin word-lists of the 1920s had {lhî “folk” >>} ᴱN. lhí “many, a number” from primitive ᴱ✶lē (PE13/148).
A noun in The Etymologies of the 1930s given as N. rhim “cold pool or lake (in mountains)” derived from the root ᴹ√RINGI “cold” (Ety/RINGI). This word is the final element of N. Mithrim “✱Grey Lake” in The Etymologies, but in later writings Tolkien explained this name differently, deriving the name from the Elves that lived around the lake, so it may have been abandoned.
Neo-Sindarin: If adapted to Neo-Sindarin, this word would be ᴺS. rim. Since √RINGI “cold” survived in later writings, this word may still be viable, though it would conflict with S. rim “host, a great number”.
