Sharing or relating to the same substance; having the same essential nature or material composition.
From Latin 'con-' (together) + 'substantivus' (relating to substance). This adjective form describes the relationship between things that share identical substance or essence.
While 'consubstantial' became famous in religious debates, 'consubstantive' is the rarer philosophical cousin—it's used in logic and metaphysics to describe how different properties or objects share the same fundamental reality.
