The character 腕 evolved from ancient pictographs depicting the human arm and hand. In Liushutong, L22695 shows an early form featuring the radical 月 (肉, meaning 'flesh/body') combined with elements representing the wrist joint or forearm. This reflects the character's core meaning of 'arm' or 'wrist.' Over centuries, the composition stabilized into the modern form 腕, where 宛 provides phonetic value while 月 (肉) maintains the semantic connection to the body. The character carries connotations of strength, skill, and capability - as one's abilities are often demonstrated through their arms and hands. Arrived in Japan: The character 腕 likely arrived in Japan during the 5th-6th centuries CE as part of the broader introduction of Chinese writing systems through Buddhist texts and cultural exchange. It became established in Japanese as 'ude' (arm) and developed additional meanings related to skill and ability, much like in Chinese.
