The most common Quenya name for the Sun derived from primitive ✶Anār, an augmented form of the root √NAR “fire” (Let/425; PE17/38; Ety/ANÁR; SD/302, 306).
Conceptual Development: This term appeared in Silmarillion drafts of the 1930s with the gloss “Heart of Flame” (LR/240) and as ᴹQ. Anar “sun” in The Etymologies of the 1930s, already with the derivation given above (Ety/ANÁR, NAR¹).
Anar noun "Sun" (ANÁR, NAR1, SA:nár; UT:22 cf. 51); anar "a sun" (Markirya); Anarinya "my Sun" (FS). See also ceuranar, Úr-anar. (According to VT45:6, Tolkien in the Etymologies mentioned anar "sun" as the name of the short vowel carrier of the Tengwar writing system; it would be the first letter if anar is written in Quenya mode Tengwar.) Compounded in the masc. name Anárion "Sun-son" (Isildur's brother, also the Númenorean king Tar-Anárion, UT:210); also in Anardil "Sun-friend" (Appendix A), a name also occurring in the form Anardilya with a suffix of endearment (UT:174, 418). Anarya noun second day of the Eldarin six-day week, dedicated to the Sun (Appendix D). Anarríma name of a constellation: *"Sun-border"??? (Silm; cf. ríma)
