AbstractA property of a space is called hereditary if each subspace of the space possesses this property. In this paper, we consider some properties which are not hereditary in general and we ask: when are they hereditary? A typical result is: a regular space is a Lindelöl p-space hereditarily if and only if the space has a countable base. Some other new results of this kind are obtained
