About
The Chinese character 醭 (bú) is a phono-semantic compound. Its left component, 酉 (yǒu), provides the semantic category of fermented liquids like wine or alcohol, while the right component, 菐 (pú), supplies the pronunciation. The character primarily refers to the mold or scum that forms on the surface of alcoholic beverages, vinegar, or soy sauce due to improper fermentation or spoilage. Its meaning has broadened somewhat over time to include similar fungal growths or white powdery coatings on other food items or damp surfaces, but its core linguistic function remains tied to spoiled liquids.
