The word 占据 is formed by combining two characters, each contributing a layer of meaning to create a single concept. The first character, 占 (zhàn), carries the core idea of claiming, seizing, or occupying, often through an assertive act. The second character, 据 (jù), adds the dimension of holding firm, relying upon, or being based on something, implying a sustained state. When merged, 占 provides the initial action of taking control, while 据 reinforces the resulting condition of maintaining that control firmly and securely, thus together forming the complete notion of "to occupy and hold".
