cloud (v.) Copy link • cloud (v.): chiefly in pass. Phr.: the sky is suddenly c.'d over, eripiunt subito nubes coelum, Virg.; tenebrae, nubes, se coelo obducunt: cf. Plin. 11, 37, 54; (or, coelum nubibus obducitur, for obduco admits both constructions); removent subeuntia nubila coelum, Ov. F. 2, 493; also simply nūbĭlat (impers.): Varr. Nūbesco, to be c.'d over, become cloudy, is of doubtful authority; and obnubilo, to becloud, appears to occur only in fig. sense (Gell.).
