The word "陈凯歌" is a Chinese personal name formed from three characters: 陈, which functions as the family surname, followed by 凯 and 歌, which together constitute the given name. 凯 carries the meaning of "triumphant" or "victorious", and 歌 means "song", so the combination 凯歌 creates the phrase "victorious song". Therefore, the name is structurally assembled by attaching a two-character meaningful given name to a single-character surname.
