This paper examines the historical development and semantic shifts of the term "metaphysics." Originally a technical library classification, the term gradually acquired philosophical connotations that obscured its etymological roots. The author analyzes the origin of the word "fysis," which in pre-philosophical times denoted a living body and the processes of birth and growth rather than inert matter. As philosophy evolved, the focus shifted from the changing nature of life to immutable reality, leading to the reinterpretation of the prefix "meta" as the Latin "super" (supernatural). The text explains how the Latin translation "natura" and the rejection of dynamism resulted in metaphysical reality being perceived as static and devoid of life. The paper further discusses Plato's eternal ideas and Aristotle's attempt to reconcile movement with theoretical knowledge through the concept of substance (substratum). This evolution ultimately transformed metaphysics into "substance metaphysics," where the real is defined as that which remains unchanging beneath the flow of transformation.
