ᴱQ. yalka n. “ice” (Category: Ice, Frost)
A noun for “ice” in the Qenya Lexicon under the early root ᴱ√ẎALA “ring, sound hollow” (QL/105). Elsewhere in the Qenya Lexicon Tolkien contrasted it with ᴱQ. helke “ice” (QL/39), and in later writings Tolkien retained helke and seems to have abandoned yalka.
