Origin

From Scots cosie, from Old Scots colsie, but ultimate derivation is unknown. Possibly of North Germanic origin, such as Norwegian kose seg (“to have a cozy time”), from Old Norse kose sig, from koselig, koslig, perhaps ultimately from Old High German kōsa; see modern German kosen (“to cuddle”).
