sinda
grey
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)

nóre
noun. country
country
The name of a land mentioned in Galadriel’s Namárië poem (LotR/337). In one place, Tolkien said it was the “name of a mythical region of shadows lying at outer feet of the Mountains of Valinor” (PE17/72). This name is a compound of sinda “grey” and nórë “country”, with the suffix -ië common in abstract nouns. In another note Tolkien said that sindanórië was an archiac formation that meant “land of greyness” and was equivalent to sindie-nóre (PE17/72), so perhaps the -ië suffix at the end was actually associated with the adjective sinda “grey”.
