Stoniest → It is formed from "stone" (from Old English *stan*, meaning a hard, solid mineral) and the suffix "-iest" (meaning most). The word "stoniest" describes something that has the most stones or is characterized by stones.
Think of 'stone' as a hard mineral, and remember that 'stoniest' means having the most stones.
