elen
noun. star
The most common Quenya word for “star”, mentioned very frequently, derived from an extended form ✶elen of the root √EL “behold” (PE17/67; WJ/360, 362). Its usual plural form is eleni, but it has an archaic plural †eldi sometimes used in verse, the result of the Ancient Quenya sound whereby [[aq|[ln] became [ld]]] after the ancient plural underwent the Quenya syncope, ✶elenī > AQ. elni; its normal modern plural form eleni was actually a reformation from the singular (PE17/57, 151; WJ/362).
Conceptual Development: This word first appeared in The Etymologies of the 1930s, though in the original entry for the root ᴹ√EL Tolkien said it was poetical and gave variants ellen and elena (Ety/EL).

†él noun "star", pl. éli given (WJ:362, EL)
él
noun. star
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.
ílë
star
ílë noun "star" (LT1:269; rather elen, él in LotR-style Quenya.)
am- (2) prefix used in comparison, "signifying addition, increase" (PE17:90), or with genitive superlative: elenion ancalima "brightest of stars" (PE17:91). Originally identical with #1 above. The form am- as such is in late Quenya only used before p and (presumably) before vowels; the longer form ama- came to be preferred before r and l; before other consonants, the prefix assumes the form an- (pronounced, but not in Romanized Quenya orthography written, añ- before c) (PE17:90-92). Phonologically we would expect am- before y- (since my is an acceptable Quenya combination); however, Tolkien used an- in the word anyára (q.v.) See an- #2 and compare ar- #2.
