ᴱQ. hilk- v. “to freeze” (Category: to Freeze)
Neo-Quenya: Since there is no sign of ᴱ√HḶKḶ in Tolkien’s later writings, I think it best is adapt this verb as ᴺQ. hel- “freeze” based directly on the later root √KHEL of ice words. Since the root is ice-related, I’d limit the meaning of this verb to the freezing of water and similar substances. For freezing weather, I’d use Q. nicu-.
