The term **幸运儿** (xìngyùn'ér) is formed through a common Chinese word-formation process where the root adjective **幸运** (lucky) is combined with the nominal suffix **儿** (ér), which literally means "child" but here functions to denote "a person characterized by." Thus, the compound literally translates to "a child of luck" or "one who is of luck," and by extension means "a lucky person" or "a fortunate one." This structure parallels English formations like "-er" in "winner," creating a noun that identifies an individual defined by the preceding descriptive element.
