uru noun "fire" (LT1:271)
úr
fire
úr noun "fire" (UR)This stem was struck out in Etym, but a word that must be derived from it occurs in LotR, so it seems that Tolkien restored it. Early "Qenya" also has Ûr, noun "the Sun" (also Úri, Úrinci ("k"), Urwen) (LT1:271). Cf. Úri.
sá noun "fire" (LT1:265; "Qenya" spelling sâ. Rather nárë in LotR-style Quenya.)
