helluin

proper name. ?Ice or Sky Blue

The name of the blue star Sirius (S/64, SI/Helluin). Its final element is almost certainly luinë “blue” (SA/luin), but the meaning of its initial element is unclear. It may be a derivation of the root √KHEL “ice”. Alternately, it might be related to ᴹQ. helle “sky” as suggested by Elaran in a private Discord chat on 2019-02-19.

Conceptual Development: In the Qenya Lexicon from the 1910s, Sirius was named ᴱQ. Nierninwa Blue-bee” (QL/65), while in the earliest Lost Tales it was called ᴱQ. Nielluin “Bee of Azure” (LT1/182) or “Blue Bee” (LT1/200), a name that also appeared in the Qenya Lexicon (QL/65).

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

luinë

luinë adj. "blue", pl. luini (PE17:66, VT48:23, 24, 28, Nam, RGEO:66). Common Eldarin luini- would also be the stem-form in Quenya (VT48:24). Compare luinincë. Apparently -luin in Illuin, the name of one of the Lamps of the Valar (q.v.), Helluin, name of the star Sirius, and Luinil, name of another blue-shining star (or planet). (SA; Luinil is tentatively identified with Neptune, MR:435). Cf. also menelluin "sky-blue", used as noun = "cornflower" (J.R.R. Tolkien: Artist & Illustrator p. 193).
