lus

root. *empty

A root in The Etymologies of the 1930s whose derivatives had to do with empty things, such as ᴹQ. lusta “void, empty”, N. lhoss “wilderness” and N. lhost “empty” (Ety/LUS). The last of these was an element in the name N. Lhothlann or Lothland “Empty and Wide” (Ety/LAD; LR/264), and Tolkien’s continued use of S. Lothlann in later versions of the Silmarillion indicate the ongoing validity of this root (S/123).

slus

root. whisper

A root in The Etymologies of the 1930s with variants ᴹ√SLUS and ᴹ√SRUS; it was glossed “whisper” with derivatives like ᴹQ. lussa- “to whisper” and ᴹQ. lusse/N. thloss/floss “whispering sound” (Ety/SLUS). The only sign of ᴹ√SRUS was the variant form N. thross of N. thloss/floss.

kum

root. void

A root in The Etymologies of the 1930s glossed “void”, with derivatives like ᴹQ. kúma “void” and N. caun “empty” (Ety/KUM). It was probably also the basis of ᴹQ. kumba in ᴹQ. saurikumba in Lord of the Rings drafts from the 1940s, unglossed but probably “✱foul-bellied” (SD/86).
