sinda (þ) adj. "grey" (PE17:72); nominal pl. Sindar used = "Grey-elves", lit. *"Grey ones"; see WJ:375. Gen. pl. Sindaron in WJ:369. With general meaning "grey" also in Sindacollo > Singollo "Grey-cloak, Thingol" (SA:thin(d), PE17:72; see also sindë, Sindicollo);†sindanórië "grey land", ablative sindanóriello "from/out of a grey country" (Nam); the reference is to a “mythical region of shadows lying at outer feet of the Mountains of Valinor” (PE17:72). However, other sources give sindë (q.v.) as the Quenya word for "grey"; perhaps sinda came to mean primarily "Grey-elf" as a noun. Derived adjective Sindarin "Grey-elven", normally used as a noun to refer to the Grey-elven language. (Appendix F)
sindarinwa (þ) adj. "Grey-elven" in the phrase hwesta sindarinwa "Grey-elven hw" (Appendix E); it may really be "Sindarin" (as a noun) with the possessive ending -va, -wa appended, hence literally "hw of [the] Sindarin [language]"
