Pronunciation
Meaning
Primary: egg
Etymology
Oracle-bone origin
蛋 has no oracle bone or bronze form and is a relatively late character, not appearing clearly until the medieval period. It is a semantic compound: the top 疋 (originally a foot, but here functioning as a phonetic/graphic element) sits above 虫 (insect, small creature), the radical used for many egg-laying animals like snakes, fish, and reptiles. The combination suggests something laid by a small creature.
Form evolution
Early texts used other words for egg, including 卵. 蛋 emerges in Song and Yuan vernacular writing and stabilises in Ming-Qing colloquial texts. There is no seal or clerical form in the classical canon; the modern regular-script shape has been essentially fixed since the Ming.
How the meaning evolved
The original sense was an egg, especially a bird or reptile egg, in contrast to the more literary 卵. In modern Mandarin 蛋 is the everyday word for egg (鸡蛋 chicken egg, 鸭蛋 duck egg) and also anything egg-shaped (脸蛋 cheek, face). It further serves as an insult suffix, as in 笨蛋 (fool) and 坏蛋 (bad guy), a colloquial use that only developed in the last few centuries.
Cultural note
The split between literary 卵 and colloquial 蛋 is still alive: biology textbooks use 卵 for ova and eggs in a technical sense, while kitchen Chinese uses 蛋. Calling someone 坏蛋 is strong in writing but fairly mild in speech, a gap that trips up learners who translate it as the harsher English equivalents.
Mnemonic
