Etymology 1Edit

From Middle French predicat (French prédicat), from post-classical Late Latin praedicatum (thing said of a subject), a noun use of the neuter past participle of praedicō (I proclaim), as Etymology 2, below.

PronunciationEdit

NounEdit

predicate (plural predicates)

  1. (grammar) The part of the sentence (or clause) which states something about the subject or the object of the sentence.
    In "The dog barked very loudly", the subject is "the dog" and the predicate is "barked very loudly".
    • 1988, Andrew Radford, chapter 8, Transformational grammar: a first course, Cambridge, UK: Cambridge University Press, page 438:
      In the light of this observation, consider Number Agreement in a sentence like:
      (120)      They seem to me [S — to be fools/a fool]
      Here, the Predicate Nominal fools agrees with the italicised NP they, in spite of the fact that (as we argued earlier) the two are contained in different Clauses at S-structure. How can this be? Under the NP MOVEMENT analysis of seem structures, sentences like (120) pose no problem; if we suppose that they originates in the — position as the subordinate Clause Subject, then we can say that the Predicate Nominal agrees with the underlying Subject of its Clause. How does they get from its underlying position as subordinate Clause Subject to its superficial position as main Clause Subject? By NP MOVEMENT, of course!
  2. (logic) A term of a statement, where the statement may be true or false depending on whether the thing referred to by the values of the statement's variables has the property signified by that (predicative) term.
    A nullary predicate is a proposition. Also, an instance of a predicate whose terms are all constant — e.g., P(2,3) — acts as a proposition.
    A predicate can be thought of as either a relation (between elements of the domain of discourse) or as a truth-valued function (of said elements).
    A predicate is either valid, satisfiable, or unsatisfiable.
    There are two ways of binding a predicate's variables: one is to assign constant values to those variables, the other is to quantify over those variables (using universal or existential quantifiers). If all of a predicate's variables are bound, the resulting formula is a proposition.
    • 1988, Andrew Radford, chapter 6, Transformational grammar: a first course, Cambridge, UK: Cambridge University Press, page 323:
      Thus, in (121) (a) persuade is clearly a three-place Predicate — that is, a Predicate which takes three Arguments: the first of these Arguments is the Subject NP John, the second is the Primary Object NP Mary, and the third is the Secondary Object S-bar [that she should resign]. By contrast, believe in (121) (b) is clearly a two-place Predicate (i.e. a Predicate which has two Arguments): its first Argument is the Subject NP John, and its second Argument is the Object S-bar [that Mary was innocent].
  3. (computing) An operator or function that returns either true or false.
