“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!”

“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].”

“A propositional variable may be treated as a nullary predicate.”

“A predicate is either valid, satisfiable, or unsatisfiable.”

“Predicates are usually found in a query's WHERE or HAVING clauses, though they can be located elsewhere (e.g. in CASE expressions).”
