The word **聋子 (lóngzi)**, meaning "a deaf person," is formed through a common Chinese morphological process where the core adjective or descriptor **聋 (lóng)**, meaning "deaf," is combined with the nominalizing suffix **子 (zi)**. This suffix **子** has no independent meaning here but functions grammatically to convert the descriptive state of being deaf into a concrete noun denoting a person characterized by that trait. Thus, the construction follows the pattern of **[attribute + 子]** to create a personhood noun, similar to words like 瞎子 (xiāzi, blind person) or 胖子 (pàngzi, fat person).
