The kanji 佐 is a 形声文字 (keisei moji), which means that it combines a phonetic component with a semantic component. The left side is the 人 (jin), meaning "person," which serves as the radical, indicating that it is related to a person. The right side is the pronunciation component, 左 (sa). 左(sa) originally meant "help," but over time it changed to imply a helper or assistant. The character 佐 was created to specifically represent "help," "assist," or "to aid" someone.
