Incapable of moving or being moved; not moving; still. This state can apply to physical objects, people, or concepts. It suggests a lack of motion, whether due to physical constraints, deliberate intent, or a state of inertia.
It also applies to the concept of something unable to change or progress. Often, 'immobile' implies a degree of fixity, stasis, or a temporary or permanent lack of movement or activity.
The degree of immobility can range from slight to complete, and the context dictates the implications of the lack of movement or change.
