Origin: A borrowing from Latin. Etymon: Latin nivālis.

Etymology: < classical Latin nivālis snowy, covered in snow, formed of snow, resembling snow < niv- , nix snow (see snow n.¹) + -ālis -al suffix¹. With sense 2 compare French nivéal flowering in winter (1831), found in snow (1840; 1831 as nival in sense ‘(of a plant) living under the snow’; compare also Middle French, French nival (of a mountain) covered in snow (1532)). Compare Italian nivale (1473–4 in an isolated attestation; otherwise a1817).

1. Snowy, resembling snow; formed from or in snow. Cf. niveous adj.

1881 Amer. Naturalist 15 519 This nival covering is not a shroud to conceal the dead, but a warm comforter spread over the earth's slumbering forces by that Great, Good Hand ‘which giveth snow like wool’.

1994 Jrnl. Mammalogy 75 420 Six of 20 nival shelters used by nonparturient females [sc. polar bears] were located on the sea ice.

2. Designating a region of perpetual snow; growing in or characteristic of such a region.
