idle

This word carries a distinct sense of wasted potential or suspended animation. When applied to people, it often suggests a lack of ambition or a purposeless drift, though it can occasionally describe a peaceful, guilt-free relaxation. It differs from being simply resting, as it implies a state of being unoccupied when one should perhaps be productive. In a mechanical sense, it describes a state of readiness without progress. An idling engine is consuming energy and creating noise but is not moving the vehicle forward. This creates a tension between the internal activity of the machine and its external stillness.
