The definition of semi-preopen sets were first introduced by Andrijevic as were is defined by :Let (X , τ ) be a topological space, and let A ⊆ X , then A is called semi-preopen set if A ⊆A¯∘In this paper, we study the properties of semi-preopen sets but by another definition which is equivalent to the first definition and we also study the relationships among it and (open, α-open, preopen and semi-p-open )sets.
