cor

noun. ring, circle

A word appearing as an element in Cormallen and translated as either “circle” or “ring” (RC/625). It is probably based on √KOR “round”.

Conceptual Development: The Gnomish Lexicon of the 1910s had G. corm “a ring, or circle; a disc” with a deleted gloss “a globe” (GL/26), likely derived from the early root ᴱ√KORO.

Neo-Sindarin: For purposes of Neo-Sindarin, I would only use cor as an element in compounds like echor. For stand-alone words, I would use corod for “circle” and [ᴺS.] corf for “(finger) ring”.

cor-

verb. to turn sour, curdle, congeal; to make cheese

echor

ring

(outer ring or circle) echor (pl. echyr). It is unclear what the Sindarin word for an ornamental ring is; the cognate of Quenya corma would be *corf (i gorf, o chorf; pl. cyrf, i chyrf, coll. pl. corvath).
