Wantonly → It is formed from "want" (from Old Norse *vanta*, meaning to lack or be without) and the suffix "-ly" (meaning in a manner of). The word "wantonly" means in a manner that lacks restraint or is without regard for consequences.
Think of lacking something ('want') and doing it in a certain way ('-ly'). This helps you remember that 'wantonly' describes actions done without restraint or care.
