The word **痞子 (pǐzi)** is formed through a morphological process combining the morpheme **痞 (pǐ)**, which originally denoted a type of abdominal mass or disease in classical Chinese but semantically shifted to mean "ruffian," "rascal," or "unprincipled behavior," with the extremely common nominal suffix **子 (zi)**. This suffix, when attached to nouns, often indicates a person belonging to a certain category, frequently carrying a colloquial or slightly pejorative nuance. Thus, **痞子** literally constructs a noun meaning "a person characterized by *pǐ*," concretely referring to a hoodlum, a petty rogue, or an unscrupulous and lazy individual, effectively encapsulating both a social role and a moral judgment in a single, solidified compound.
