鸡肉
jī ròu · HSK 3
meat
🍗 鸡肉 = 鸡 (chicken) + 肉 (meat)
鸡 means chicken (the bird) and 肉 means meat/flesh, so 鸡肉 is literally chicken-meat — the edible form. Same pattern as 牛肉 (beef) and 猪肉 (pork).
鸡 — 又 (hand) + 鸟 (bird), simplified from 雞
Originally written 雞, a phono-semantic compound: 鳥 'bird' gives the meaning, while 奚 supplied the sound. The simplified form 鸡 replaces 奚 with 又 (a hand) as a sign component and uses the simplified bird radical 鸟. The character has always meant 'chicken'.
肉 — pictograph of a slab of meat with ribs/striations
肉 is a pictograph originally depicting a piece of butchered meat, showing the outer cut and the striations of muscle or ribs inside. The character has meant 'flesh' or 'meat' since oracle bone times. As a radical it is usually written 月 on the left or bottom of characters relating to the body (e.g. 肝, 胃).
