The Chinese word "讯号" (xùnhào), meaning "signal" (as in a transmitted electrical or electromagnetic signal), is a modern compound formed by combining two meaningful characters: "讯" (xùn), which carries connotations of "message", "information", or "communication", and "号" (hào), which means "sign", "mark", or "signal". Together, they semantically merge to create a term that specifically denotes a "communicated sign" or a "message-bearing signal", reflecting its technical application in telecommunications, electronics, and computing. This construction follows the common Chinese linguistic pattern of combining related morphemes to generate a precise, composite meaning for a new concept.
