A noun in The Etymologies of the 1930s glossed “herb” derived from ᴹ✶SALÁK-(WĒ) and cognate to ᴹQ. salqe “grass” (Ety/SALÁK). Its Noldorin plural was seleb, but if adapted into Sindarin its plural would be ✱selaib.
Conceptual Development: A likely precursor is ᴱN. {halo >>} halb “grass, long mowing grass” from Early Noldorin word lists of the 1920s, which had a Quenya cognate ᴱQ. salqe (PE13/147). The variant half “grass” from elsewhere in the same document was likely also related (PE13/147). See also G. salc “green cut grass” from the 1910s.
A word appearing in The Etymologies of the 1930s as a derivative of ᴹ√KUL “gold (metal)” (Ety/KUL). Tolkien updated this entry to change the root’s gloss to “golden-red”, after which its Noldorin derivative became N. coll “red”, while elsewhere in The Etymologies the word for “gold (as metal)” became N. malt (Ety/SMAL).
Conceptual Development: The Gnomish Lexicon of the 1910s had G. †culu used poetically for “gold”, cognate to ᴱQ. kulu “gold” (GL/27) and thus derived from the same early root ᴱ√KULU (QL/49). G. culu was also given as an example noun for declensions in the contemporaneous Gnomish Grammar (PE11/14).
