The kanji 雄 is a 形声文字 (keisei moji), which means that it is a character that combines a semantic component (a meaning component) and a phonetic component (a sound component). The left side is the radical 隹 (ふるとり), representing a short-tailed bird. The right side is the component 生 (せい), which conveys the sound ユウ (yuu). Therefore, this character was created to indicate a male bird or an animal. Its meaning then expanded to encompass the idea of masculinity, strength, and superiority.
