How this kanji evolved

Explore each form from the oldest known stage to today.

The character 固 evolved from ancient pictographs depicting a fortified enclosure or stronghold. In its earliest forms found in oracle bone script, it showed walls surrounding a protected area, conveying meanings of strength, firmness, and security. The character developed through bronze script into clerical script, gradually simplifying while maintaining its core concept of solidity and permanence. The modern form consists of 囗 (enclosure) surrounding 古 (ancient), suggesting something that has been ancient and enduring - thus solid and unchangeable. Throughout Chinese history, 固 has carried meanings of firmness, stability, stubbornness, and reliability, appearing in compounds like 固定 (fixed), 坚固 (sturdy), and 固执 (stubborn). Arrived in Japan: The character 固 arrived in Japan during the 5th-6th centuries CE, along with the broader introduction of Chinese writing system and literature through Korean scribes and Chinese Buddhist texts. It was formally incorporated into the Japanese writing system during the Asuka period (538-710 CE) as part of the mass importation of Chinese culture, technology, and governance systems. The character maintained similar meanings in Japanese, appearing in early Japanese texts like the Kojiki (712 CE) and Nihon Shoki (720 CE), and continues to be used in modern Japanese with readings 'ko' and 'kata(meru)'.
