The character "雄" is formed from the radical "隹" meaning "bird" and the phonetic component "厷" suggesting sound and contributing to its meaning of strength or masculinity, while "鹰" is composed of the radical "鸟" meaning "bird" and the phonetic component "䧹" indicating pronunciation; combined as "雄鹰", the first character modifies the second to denote a powerful or majestic eagle.
