About
The character 馊 is a phono-semantic compound, with the left radical 饣 (shí, food) indicating a connection to eating or food, and the right component 叟 (sǒu, old man) providing the phonetic element. Its traditional form is 餿, using the unsimplified food radical 食. The primary meaning refers to food that has spoiled, soured, or become rancid. This sense later extended metaphorically to describe ideas or suggestions as bad, unworkable, or rotten, commonly used in phrases criticizing poor advice or terrible plans. The transition moved from a physical state of decay to an abstract judgment of quality.
