Abstract :In this paper, we present a new concept of inner amenability for a non- empty arbitrary subset A of discrete semigroup S called A-inner amenablility. This condition is considerably weaker than ordinary inner amenability. Further, we give  some equivalent conditions between this version of inner amenability and Flner`s condition.
