The word 李登辉 is a Chinese personal name formed from three characters: 李, which serves as the surname and means "plum"; 登, meaning "to ascend" or "climb"; and 辉, meaning "brightness" or "radiance". The name is constructed by placing the surname 李 first, followed by the given name 登辉, where the characters 登 and 辉 are combined to convey a compounded meaning, such as "ascending to brightness" or "achieving splendor".
