The most common Sindarin name for the Sun derived from primitive ✶Anār, an augmented form of the root √NAR “fire” (PE17/38; Ety/ANÁR; SD/302-303, 306). The o is the result of ancient ā becoming au and then this au becoming o in polysyllables.
Conceptual Development: The term Anor was first mentioned in conjunction with early tales of Númenor (LR/41). It briefly appeared as N. {ánar >>} Anar “sun” in The Etymologies of the 1930s under the entry for ᴹ√NAR (Ety/NAR¹; EtyAC/NAR¹), but as Anor under ᴹ√ANÁR (Ety/ANÁR). In The Notion Club Papers of the 1940s it was Anor, archaic †Anaur (SD/302-303, 306) and it retained this form thereafter.
*ŷr (construct yr; no distinct pl. form; coll. pl. yrath). Suggested Sindarin form of ”Noldorin” iôr.
