Frostiness → It is formed from "frost" (from Old English *forst*, meaning frozen dew or ice) and "-iness" (meaning the quality of being). The word "frostiness" refers to the quality of being frosty or cold, often in a literal sense of temperature or a metaphorical sense of demeanor.
Think of 'frost' as the coldness that covers things, and '-iness' indicates a quality. So, frostiness helps you remember the quality of being cold or icy.
