ringa adj. "cold" (Markirya); the Etymologies gives ringë (RINGI), but it seems that ringa is to be preferred (cf. Ringarë below). Yá hrívë tenë, ringa ná "when winter comes, it is cold" (VT49:23). According to VT46:11, Tolkien originally used the form ringa in Etym as well; later he would restore it. - In early "Qenya", ringa is glossed "damp, cold, chilly" (LT1:265)

yelwa (2) adj. "cold" (LT1:260 this "Qenya" word is apparently obsoleted by # 1 above. In LotR-style Quenya, the regular term for "cold" seems to be ringa.)
ringë adj. "cold", also ringa (which form is to be preferred; cf. Ringarë in LotR). In the Etymologies as printed in LR, ringë is also given as a noun "cold pool or lake (in mountains)", but according to VT46:11 this noun should read ringwë. (RINGI)
