The word "李娜" is formed by combining two Chinese characters: "李", a character composed of "木" (meaning tree) and "子" (historically used for sound), denoting the surname Li and originally meaning plum; and "娜", a character composed of "女" (meaning woman) and "那" (providing phonetic approximation), used as a feminine given name. Together, they constitute a full personal name with "李" as the surname and "娜" as the given name.
