Predicate Logic. A predicate is a statement that contains variables (predicate variables) and that may be true or false depending on the values of these predicate variables. Predicates are the propositions containing variables and represent properties or relations among objects.

Predicate Logic has two such quantifiers: ∀ (the universal quantifier) and ∃ (the existential quantifier). Since a predicate can combine with more than one variable, it is necessary to write the variable immediately after the quantifier to indicate which variable the quantifier interacts with.
