    In this paper we define pairwise expandable spaces and study their properties and their relations with other bitopological spaces several exam-ples are discussed and many will known theorems are generalized concerning pairwise expandable spaces and we shall investigate subspaces of pairwise expandable space and also bitopological spaces which are related to pairwise expandability.

    Keywords: Pairwise expandable, Pairwise–normal, Pairwise paracompact, Bitopological.
