鷄

A phono-semantic compound:

鳥 (조, “bird”) provides the meaning (a type of bird).

奚 (해, “how/what”) provides the sound.

In oracle bone script (甲骨文 jiǎgǔwén), the character already depicted a chicken.

鷄 is one of the basic characters taught in HSK Level 1 (beginner Chinese proficiency).

While it primarily means “chicken,” it is also used euphemistically in Chinese to refer to the male genitalia, instead of the vulgar word 屌.

雞 is a variant form using 隹 (짧은 꼬리 새, small bird) as the semantic component.

In Taiwan, Hong Kong, and other regions using traditional characters, 雞 is the standard form.
