Smartest → It is formed from "smart" (from Old English *smeart*, meaning to be able or to be clever) and the suffix "-est" (meaning the most). The word "smartest" refers to the person who is the most clever or able among a group.
Think of someone who is the 'most clever' — 'smart' means clever, and '-est' indicates the highest degree. This helps you remember that 'smartest' refers to the person who is the most clever.
