The word 依据 is formed by combining two independent characters, each contributing a core conceptual layer to create a unified, abstract meaning. The first character, 依 (yī), carries the inherent idea of "leaning on" or "depending on", establishing a relationship of reliance. The second, 据 (jù), intrinsically means a "foundation", "basis", or "that upon which something rests". Their fusion is not merely additive but synergistic, where 依 conceptually leans upon the substantive foundation of 据, resulting in the integrated notion of "that which serves as the dependable basis or authoritative foundation for something", effectively capturing the essence of "basis" or "according to".
