The adjective cozy describes being comfortable and warm, like when you feel cozy curled up on the couch under a soft blanket, in front of a roaring fire.
"Isn't this cozy?" If you hear these words, you might be in a friendly, casual place where everyone feels welcome. Or, perhaps you are in a small cabin that is warm and dry as they rain pours down outside. Or you have just stumbled upon the judge of a writing contest having dinner with one of the aspiring novelists — cozy can also mean "scheming." And as a noun? A cozy is a padded cloth used to keep a teapot warm.
