The spelling cosy predominates in British English, and cozy in American English.
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”).
