= Predicate variable
{wiki=Predicate_variable}
In the context of logic and mathematics, a **predicate** is a statement or function that expresses a property or characteristic of objects from a certain domain. A predicate can take one or more arguments (variables) and evaluates to either true or false depending on the values of those variables. A **predicate variable** is essentially a placeholder for a predicate.
