Definition: Hereditary and Weakly Hereditary Properties
If every subspace of a topological space (X,\mathcal O) has a property of X, this property is said to be hereditary.
A property of X is said to be weakly hereditary, if every closed subset U\subseteq X, considered as a subspace of X has this property.
