The Chinese word 性病 (xìngbìng), meaning "venereal disease" or "sexually transmitted disease," is a compound noun formed through semantic combination. The first character, 性 (xìng), carries the primary meaning of "sex" or "sexual nature," while the second character, 病 (bìng), straightforwardly means "disease" or "illness." When combined, the two morphemes create a precise and direct term where 性 modifies 病, specifying the category of illness as one related to sexual activity, thus forming a logical and readily understandable word through the straightforward compounding of its meaningful parts.
