In this paper, the boundedness properties of commutators generated by b and intrinsic square functions in the endpoint case are discussed, where b∈ BMO(\mathbb Rn). We first establish the weighted weak Llog L-type estimates for these commutator operators. Furthermore, we will prove endpoint estimates of commutators generated by BMO(\mathbb Rn)functions and intrinsic square functions in the weighted Morrey spaces L1,κ(w) for 0
