Root Explanation

Frostiest → It is formed from "frost" (from Old English *forst*, meaning frozen dew or ice) and the suffix "-iest" (meaning most). The word "frostiest" means having the most frost or being the coldest in terms of frost accumulation.

Memory Tip

Think of 'frost' as the icy condition and '-iest' indicating the highest degree, so 'frostiest' means the most icy or cold.
