nárë

flame

nárë, also short nár, noun "flame" (NAR1, Narqelion). Translated "fire" in some names, see Aicanáro, Fëanáro (where nár apparently has the masculine ending -o, though in the latter name it may also be the genitive ending since Fëa-náro** is translated "Spirit of Fire"). At one point, Tolkien mentioned "nār-" as the word for "fire (as an element)" (PE17:183). Cf. ruinë** as the word for "a fire" (a concrete instance of fire) in the same source.
