Predicado
A Predicate is a sentence-forming Relation. Each tuple in the Relation is a finite, ordered sequence of objects. The fact that a particular tuple is an element of a Predicate is denoted by '(*predicate* arg_1 arg_2 .. arg_n)', where the arg_i are the objects so related. In the case of BinaryPredicates, the fact can be read as `arg_1 is *predicate* arg_2' or `a *predicate* of arg_1 is arg_2'.
Relationships      
Parents InheritableRelation The class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
  Relacao The Class of relations. There are two kinds of Relation: Predicate and Function. Predicates and Functions both denote sets of ordered n-tuples. The difference between these two Classes is that Predicates cover formula-forming operators, while Functions cover term-forming operators.
Children Predicado BinarioA Predicate relating two items - its valence is two.
 ClosedWorldPredicate
 LogicalOperatorThis Class comprises all of the logical operators (viz. 'and', 'or', 'not', '=>', and '<=>').
 Predicado QuaternarioThe Class of Predicates that require four arguments.
 Predicado QuinquenarioThe Class of Predicates that require five arguments.
 Predicado TernarioThe Class of Predicates that require exactly three arguments.
