Definition: Fog
Etymology
Origin uncertain; but probably of North Germanic origin. Probably from or related to Danish fog (“spray, shower, drift, storm”), related to Icelandic fok (“spray, any light thing tossed by the wind, snowdrift”), Icelandic fjúka (“to blow, drive”), from Proto-Germanic *feukaną (“to whisk, blow”), from Proto-Indo-European *pug- (“billow, bulge, drift”), from *pew-, *pow- (“to blow, drift, billow”), in which case related to German fauchen (“to hiss, spit, spray”).
