Whimsically → It is formed from "whimsy" (from Old English *hwimsy*, meaning a fanciful idea or notion) and the suffix "-ically" (meaning in a manner relating to). The word "whimsically" means in a fanciful or playful manner.
Think of a fanciful idea ('whimsy') and how it is expressed 'in a manner' ('-ically') — that's why whimsically means to act in a playful or fanciful way.
