The main aim of the study of this paper is to work with the properties of frontier and exterior in intuitionistic supra topological spaces. Considering this we have introduced intuitionistic supra -frontier and intuitionistic -exterior in intuitionistic supra topological space. We have also deliberated the properties of intuitionistic suppra -frontier and intuitionistic supraexterior in intuitionistic supra topological space. The comparative study has been done with the use of intuitionistic
