A root for “fire” first appearing as ᴹ√NAR “flame, fire” in The Etymologies of the 1930s along with derivatives like ᴹQ. nár(e)/N. naur “flame” (Ety/NAR¹). There was also an augmented variant ᴹ√ANÁR that served as the basis for “Sun” words: ᴹQ. Anar and N. Anor (Ety/ANÁR). These roots and the various derivatives continued to appear in Tolkien’s later writings in the 1950s and 60s (PE17/38; Let/425), and in one place Tolkien specified that nār- was “fire as an element” as opposed to √RUYU for an actual blaze.

This root was the basis for Elvish words having to do with “running” and (in earlier notes) “rolling” for much of Tolkien’s life. It first appeared as ᴱ√NORO “run, go smoothly, ride, spin” in the Qenya Lexicon of the 1910s (QL/67), and it had derivatives in the contemporaneous Gnomish Lexicon like G. nor- “run, roll” (GL/61) as well as dronn “race, course, track” < ✱n’rond- (GL/31). ᴹ√NORO “run as of wheels, roll along” reappeared in a page of roots in the Quenya Verbal System of the 1940s, though this page was deleted (PE22/127 note #152). √NOR “run (or leap: of animals, men etc.)” also appeared in some etymological notes associated with The Lord of the Rings, probably from the late 1950s (PE17/168).
Neo-Eldarin: For purposes of Neo-Eldarin, I’d retain both senses “run” and “roll” for this root, but limit the latter to the rolling of wheels as an extrapolation from the movement of legs.
