The predicate is one of the two main parts of a sentence (the other being the subject, which the predicate modifies). [ a ] The predicate must contain a verb , and the verb requires or permits other elements to complete the predicate, or else precludes them from doing so.
First-order logic—also called predicate logic, predicate calculus, quantificational logic—is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science. First-order logic uses quantified variables over non-logical objects, and allows the use of sentences that contain variables.
A predicate is a statement or mathematical assertion that contains variables, sometimes referred to as predicate variables, and may be true or false depending on those variables’ value or values. In propositional logic, atomic formulas are sometimes regarded as zero-place predicates. [1] In a sense, these are nullary (i.e. 0-arity) predicates.
In linguistics and grammar, a sentence is a linguistic expression, such as the English example "The quick brown fox jumps over the lazy dog."In traditional grammar, it is typically defined as a string of words that expresses a complete thought, or as a unit consisting of a subject and predicate.
As example, a knowledge base may contain complete information for predicates R and S, while nothing is asserted for predicate T. Then consider the following queries: Q1 :- R(x), S(x) Q2 :- R(x), T(x) For Query 1, the knowledge base would return a complete answer, as only predicates that are themselves complete are intersected. For Query 2, no ...
The predicate is a verb phrase that consists of more than one word. In the backyard, the dog barked and howled at the cat. This simple sentence has one independent clause which contains one subject, dog, and one predicate, barked and howled at the cat. This predicate has two verbs, known as a compound predicate: barked and howled. (This should ...
A variant of first-order logic restricted to predicates that take only one argument, focusing on properties of individual objects rather than relations between them. monadic function See unary function. monadic predicate A predicate that takes a single argument, used to express properties of objects or entities within a domain of discourse. [195]
In many modern grammars (for instance in those that build on the X-bar framework), the object argument of a verbal predicate is called a complement. In fact, this use of the term is the one that currently dominates in linguistics. A main aspect of this understanding of complements is that the subject is usually not a complement of the predicate ...
