A word appearing as G. norn “wheel” in the Gnomish Lexicon related to G. nor- “run, roll” (GL/31), and thus likely derived from the early root ᴱ√NORO “run, go smoothly, ride, spin, etc.” from the contemporaneous Qenya Lexicon (QL/67). ᴱN. norn also appeared in Early Noldorin Word-lists of the 1920s, but there it was untranslated (PE13/151).
Neo-Sindarin: The root √NOR was associated with both “run” and “roll” as late as 1948 (PE22/127), so I would retain ᴺS. norn “wheel” for purposes of Neo-Sindarin.
