The kanji 付 is a phono-semantic compound (形声文字 - keisei moji). The left side is the radical "亻" (にんべん - ninben), which is a simplified form of 人 (person) and provides the semantic component, indicating that the action involves people or an action done by a person. The right side is "寸" (sun), which provides the phonetic component and also suggests "a little" or "a small amount." The combination of these parts originally depicted someone placing something (perhaps a small amount) onto something else. Over time, this evolved to represent the concept of attaching or adding.
