Etymology

From dialectal English snug (“tight, handsome”), perhaps from Old Norse snøggr, from Proto-Germanic *snawwuz (“short, quick, fast”). Compare Icelandic snöggur (“smooth”), Danish snög (“neat”), Swedish snygg (“handsome, nice-looking”). Compare also English snudge (“to nestle, remain snug and quiet”).
