Foolisher → The word is formed from "fool" (from Old English *fola*, meaning a person lacking in judgment or sense) and the suffix "-ish" (meaning having the quality of). Thus, "foolisher" describes someone who has the quality of being more foolish or silly than another.
Think of someone who is 'more foolish' — 'fool' refers to a lack of sense, and '-ish' suggests having that quality. This helps you remember that 'foolisher' means someone who is more foolish.
