Whimsical → It is formed from "whimsy" (from Old English *hwimor*, meaning a sudden desire or fancy) and the suffix "-ical" (meaning pertaining to or relating to). The word "whimsical" describes something that is characterized by playful or fanciful ideas or behavior.
Think of a sudden 'fancy' or 'desire' ('whimsy') that is 'pertaining to' ('-ical') playful ideas — that's why whimsical means playful or fanciful.
