About
The character "酮" is a phono-semantic compound devised for modern scientific use, constructed from the semantic component 酉, which traditionally relates to fermented liquids and organic compounds, and the phonetic component 同, guiding its pronunciation as "tóng". Its etymology is tied to the late adoption of Western chemical concepts, specifically representing the ketone functional group in organic chemistry, a meaning absent from classical language. The structural choice aligns with a broader pattern where 酉 appears in characters for oxygenated organic substances, such as alcohols and aldehydes, ensuring conceptual coherence within the chemical lexicon. Since its creation, the character has maintained this specialized semantic domain without notable alteration, reflecting a deliberate and stable incorporation into technical terminology.
