The noun 'Verschiebung' (postponement/shift) is derived from the verb 'verschieben' (to move/postpone). This consists of the prefix 'ver-' and the verb 'schieben' (to push, to move). A 'Verschiebung' is therefore the result of the action of 'pushing' something to another place or to another time.
Die Verschiebung des Schranks war sehr anstrengend.
Moving the cabinet was very exhausting.
'Verschiebung' (postponement/shift) is often used with the preposition 'von' (of/from) or a genitive to say what is being moved or postponed. With 'auf' (to/until) or 'um' (by), the new time or the duration of the postponement is indicated.
Die Verschiebung des Treffens auf nächste Woche passt mir gut.
The postponement of the meeting until next week works well for me.
In connection with appointments and dates, 'Verschiebung' (postponement) is frequently used for events such as a flight, a meeting, an event, or a deadline.

In scientific or technical contexts such as geology, physics, or medicine, 'Verschiebung' (shift/displacement) refers to a physical change in position.

In the figurative sense, the word is often combined with abstract concepts, for example 'Verschiebung der Machtverhältnisse' (shift in the balance of power), 'Verschiebung der Prioritäten' (shift in priorities), or 'Verschiebung des Fokus' (shift in focus).

movement
'die Bewegung' and 'die Verschiebung' can both describe something changing its position. 'Bewegung' is more general: something moves, but the direction and destination do not have to be especially important. 'Verschiebung' emphasizes more strongly that something is shifted or relocated from one place to another. In a figurative sense, 'Verschiebung' can also mean that, for example, priorities or opinions move in a different direction. Learners may confuse the words because both express change. If only the act of moving is important, 'Bewegung' fits. If the new position or relocation is important, 'Verschiebung' fits better.
