Origin of 酐

The character 酐 is a compound formed from the radical 酉, which originally depicted a wine jar and is associated with chemical or fermented substances, combined with 干 (dry). Together, they suggest a dry chemical substance, namely an anhydride, which is a compound derived from an acid by removing water.

💡 Memory Tip: Picture a wine bottle (酉) that has completely dried out (干), leaving behind a white powdery residue—anhydride.
