The Chinese word **残废 (cánfèi)** is formed through the compounding of two morphemes: **残 (cán)**, meaning "injured," "incomplete," or "mutilated," and **废 (fèi)**, meaning "disabled," "useless," or "wasted." When combined, the term literally conveys the idea of being "damaged and rendered useless," specifically referring to a person with a physical disability that impairs function. Historically, it was a direct clinical or descriptive term, but in modern usage, it is widely considered derogatory and offensive, having been replaced by more respectful terms such as **残疾 (cánjí)**, which means "disabled," focusing on the condition rather than a perceived lack of usefulness.
