The word "伤者" is a standard Chinese compound noun formed by combining the morpheme **伤** (shāng), meaning "injury" or "to wound," with the nominalizing suffix **者** (zhě), which means "one who" or "the person associated with." Therefore, the construction follows a common grammatical pattern where "者" is attached to a verb or adjective to create an agent noun, resulting in the meaning "the injured one" or "the wounded person." It is a formal and concise term frequently used in news reports, legal documents, and medical contexts to refer to individuals who have sustained injuries.
