This paper introduces a new space based on a generalized neighbourhood system using the concept of a supra topology, termed a supra approximation space (briefly AS). We investigate several properties of AS and compare its advantages with those of the classical neighbourhood approximation space. Furthermore, we define and study a novel class of separation axioms using -open in a supra approximation space (AS). Finally, we explore some of their properties in the context of information system, particularly in approximation process of approximation and definability.
