About
This phono-semantic compound combines the enclosure radical 囗, suggesting walls or a protected boundary, with the phonetic component 古 (gǔ, "ancient") inside. The outer structure implies solidity and security, directly supporting the core meaning of firmness and stability. Originally describing physical strength, like a sturdy fortress, the sense extended metaphorically to abstract firmness, such as stubbornness or resolute determination. It also commonly functions as an adverb meaning "originally" or "undoubtedly".
