An archaic or poetic word for star (WJ/362), somewhat common in compounds but in ordinary speech typically appearing as elen. It was derived directly from the primitive root √EL “behold”, the basis for other star words (PM/340; WJ/360).
Conceptual Development: This word first appeared as poetical ᴹQ. él “star” in The Etymologies of the 1930s, already with the derivation given above, though in this document the root ᴹ√EL meant “star” (Ety/EL), a common gloss for the root in later writings as well.
