Predicate (grammar) The term predicate is used in two ways in linguistics and its subfields. The first defines a predicate as everything in a standard declarative sentence except the subject, and the other defines it as only the main content verb or associated predicative expression of a clause. Thus, by the first definition, the predicate of ...
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, so that rather than ...
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.
Predicative expression. A predicative expression (or just predicative) is part of a clause predicate, and is an expression that typically follows a copula or linking verb, e.g. be, seem, appear, or that appears as a second complement of a certain type of verb, e.g. call, make, name, etc. [ 1] The most frequently acknowledged types of ...
Predicate crime. In the criminal law of the United States, a predicate crime or offense is a crime which is a component of a larger crime. The larger crime may be racketeering, money laundering, financing of terrorism, etc. [ 1] For example, to violate the Racketeer Influenced and Corrupt Organization Act (RICO), a person must "engage in a ...
propositional logic, Boolean algebra, first-order logic. ⊥ {\displaystyle \bot } denotes a proposition that is always false. The symbol ⊥ may also refer to perpendicular lines. The proposition. ⊥ ∧ P {\displaystyle \bot \wedge P} is always false since at least one of the two is unconditionally false. ∀.
In linguistics, an argument is an expression that helps complete the meaning of a predicate, [ 1] the latter referring in this context to a main verb and its auxiliaries. In this regard, the complement is a closely related concept. Most predicates take one, two, or three arguments. A predicate and its arguments form a predicate-argument structure.
Nominal sentence. In linguistics, a nominal sentence (also known as equational sentence) [ 1] is a sentence without a finite verb. [ 2] As a nominal sentence does not have a verbal predicate, it may contain a nominal predicate, an adjectival predicate, in Semitic languages also an adverbial predicate or even a prepositional predicate.
