The aim of this paper is to study the class of N-scattered spaces, i.e. the spaces whose nowhere dense subsets are scattered. The concept was recently used in a decomposition of scatteredness — a topological space (X,τ) is scattered if and only if X is α-scattered (= its α-topology is scattered) and N-scattered.
