Hurtfully means “in a way that wounds someone’s feelings” — words or acts that sting, offend, or cut. She spoke hurtfully. The joke landed hurtfully. It is about the heart, not a broken arm. The word is correct but not everyday; many people would say unkindly, cruelly, or in a hurtful way instead. You will meet it more in careful writing than in chat. It is stronger than merely rudely: rude can be clumsy or loud; hurtfully points to real upset. Though actually, it is not the same as painfully. Painfully is the body, or a hard effort. Hurtfully is the hurt you feel inside when someone is unkind.

傷人地；令人難受地
