Quettaparma Quenyallo

ílë noun "star" (LT1:269; rather elen, él in LotR-style Quenya.)

ilfirin adj. "immortal" (PHIR)

ilin adj. "pale blue" (GLINDI)

illi noun "all" (as independent noun, apparently treated as a plural form). Imb' illi "among all" (VT47:30)

[-illo “you (two)”, abandoned promoninal ending for the polite 2nd person dual; in later sources the relevant ending is rather -stë (VT49:48). This -illo was changed from -llo. Compare -ilco.]

illon pl. relative pron. in ablative: "from whom", pl. (VT47:11). See i #2 (relative pronoun).

Illuin place-name, name of one of the Lamps of the Valar; apparently incorporating the element luin "blue" (Silm): hence *“all-blue”?

illumë adv. "always" (VT44:9)

ilm- stem appearing in Ilmen, the region above the air where the stars are, in Ilmarë, name of a Maia, and in Ilmarin "mansion of the high airs", the dwelling of Manwë and Varda upon Oiolossë (SA)

Ilma noun "starlight" (GIL)

Ilmarë noun "starlight", also fem. name, referring to a Maia (GIL, SA:ilm-)

Ilmarin noun "mansion of the high airs", the dwelling of Manwë and Varda upon Oiolossë (SA:ilm-)

ilmen region above air where stars are (WIL, SA:ilm-); place-name Ilmen-assa "Chasm of Ilmen" (GAS)

*ilpirin (hypothetical form; the word actually appears in Q as ilfirin) adj. "immortal" (PHIR)

ilqua ("ilqa") noun "everything" (IL, VT45:24), "all" (FS); ilquainen ("ilqainen") a word occurring in Fíriel's Song, translated "to all". It would appear to be ilqua "all" with a dative pl. ending. However, in Tolkien's later Quenya -inen is the ending for instrumental pl. (FS)
