A predicate in logic is an expression that denotes a property or relation that a subject can have. For example, in the statement 'Socrates is a philosopher,' 'is a philosopher' is a predicate. Predicates often include variables for more generalized expressions, like 'is a parent(x)' where 'x' can be any subject.
