Which term signifies something intrinsic or inherent as remaining?

The term "residual" refers to something that remains after the primary component has been removed or has gone, indicating an intrinsic quality that persists. In various contexts, it can describe leftover substances, elements, or qualities that continue to exist, highlighting their inherent nature. For example, residual value may refer to the worth of an asset that continues to hold some value even after depreciation.

The other terms do not convey the same meaning. "Aesthetic" relates to beauty or taste, "sect" refers to a group or division within a larger context, often used in religious terms, and "wry" describes a dry, especially mocking humor or a twisted expression. These definitions do not capture the concept of something that is intrinsic or inherent, as "residual" does, making it the most fitting choice.
