conceptual

This term describes things that exist in the mind as a framework or a blueprint. It suggests a level of abstraction where the focus is on the logic, the theory, or the overarching vision rather than the practical execution or the tangible materials.

In a professional or creative setting, calling something conceptual often implies it is a prototype or a theoretical model. It signals that the idea is not yet grounded in reality or is intentionally designed to challenge traditional perceptions of a subject.
