About
The character 蛎, whose traditional form is 蠣, is a phonetic-semantic compound with the radical 虫 classifying it as a creature or invertebrate and the component 厲 serving primarily a phonetic function, later simplified to 厉. Its meaning has been consistently associated with oysters, specifically within the compound 牡蛎, reflecting its etymological role in denoting this shelled mollusk. The structural evolution from the traditional to the simplified form involved a reduction in the complexity of the phonetic element while maintaining the semantic indicator and the character's specific referent.
