Predicate (mathematics) 

In mathematics, a predicate is either a relation or the boolean-valued function that amounts to the characteristic function or the indicator function of such a relation.

A function P: X→ {true, false} is called a predicate on X. When P is a predicate on X, we sometimes say P is a property of X.
