The kanji 徐 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side is a part of the radical 彳 (gyō nin ben), representing "walking" or "movement". The right side is 余 (yo), which is the phonetic component, indicating the sound and contributing to the overall meaning. The combination suggests walking or moving slowly and deliberately. This hints at the origin where the 余 component was likely related to "surplus" or "remaining", implying a slow, lingering action or process.
