Sense: adjective/1
Painful is the broad everyday word when something makes the body hurt or causes deep emotional hurt. It can describe an injury, a medical treatment, a memory, or a loss. Sore is narrower and usually describes a body part that hurts when touched or moved, such as a sore knee or throat. Hurtful is mainly for words or actions that wound someone's feelings, so a hurtful remark is not physically painful. Distressing is more formal and stresses worry, shock, or sadness. Agonizing is much stronger than painful and suggests extreme suffering or a very hard wait. Compare: a painful injection, a sore shoulder, a hurtful comment, a distressing report, and an agonizing delay.
Etymology
Painful was formed in Middle English from pain and the suffix -ful. Pain came into English through Old French from Latin poena, which first meant a penalty and later also suffering, while -ful is an Old English ending meaning 'full of'. So painful originally meant 'full of pain' or 'bringing pain'.
