  Recently, Acharjee et al. [S. Acharjee, M. \"Ozko\c{c} and F. Y. Issaka,
Primal topological spaces, arXiv:2209.12676[math.GM]] introduced a new
structure in topology named primal. Primal is the duel structure of grill. The
main purpose of this paper is to introduce an operator using primal and obtain
some of its fundamental properties. Also, we define the notion of topology
suitable for a primal. We not only obtain some characterizations of this new
notion, but also investigate many properties.
