The word 离开 is formed by combining two distinct characters, each contributing a core aspect of motion to create a unified concept. The first character, 离, carries the inherent meaning of departing, separating, or moving away from a point of origin or attachment. It is then paired with 开, which fundamentally means to open, to start, or to create distance by moving apart. When fused, the sequence conceptually moves from the initial state of separation (离) into the consequent action of creating an open gap or distance (开), picturing a single, fluid action of leaving and moving away.
