单词 subniveal
释义

subnivealadj.

Brit. /sʌbˈnɪvɪəl/, U.S. /səbˈnɪviəl/, /səbˈnɪvjəl/
Origin: A borrowing from Latin, combined with English elements; perhaps modelled on a French lexical item. Etymons: sub- prefix, Latin niv- , nix , mastoideal adj., marmoreal adj.
Etymology: < sub- prefix + classical Latin niv-, nix snow (see nival adj.) + -eal (in e.g. mastoideal adj., marmoreal adj., etc.), perhaps after French nivéal (see nival adj.). Compare earlier subnivean adj., subnival adj.Post-classical Latin subniveus (1761 or earlier, frequently in botanical and zoological contexts) is only attested in the sense ‘somewhat snow-white’.
1. Existing, living, or carried out underneath snow; = subnivean adj.
ΘΚΠ
the world > the earth > weather and the atmosphere > weather > precipitation or atmospheric moisture > snow > [adjective] > under the snow
