This was the word for “ice” in Sindarin and its precursors. It appeared with the gloss “ice” in notes on the Common Eldarin Article (CEA) from 1969 (PE23/139). N. heleg “ice” appeared in The Etymologies of the 1930s under the root ᴹ√KHELEK of the same meaning (Ety/KHELEK). G. heleg “ice” also appeared in the Gnomish Lexicon of the 1910s along with a variant helc, both under primitive χele-k (GL/48). This is clearly related to the early root ᴱ√HELE as first suggested by Christopher Tolkien (LT1A/Helkar; QL/39).
In CEA from 1969, Tolkien somewhat cryptically translated its plural form i·chelig as “ice-pinnacle”. Since “ice” is mass noun, it would not ordinarily have a plural form, so perhaps Tolkien meant that when used in the plural it referred to peak(s) of or covered by ice: “the ices”.
