Along with numerals, and special-purpose words like some, any, much, more, every, and all, they are Quantifiers. Quantifiers are a kind of determiner and occur in many constructions with other determiners, like articles: e.g., two dozen or more than a score. Scientific non-numerical quantities are represented as SI units.
In logic, a quantifier is an operator that specifies how many individuals in the domain of discourse satisfy an open formula.For instance, the universal quantifier in the first order formula () expresses that everything in the domain satisfies the property denoted by .
In other words, an operator has scope of operation, or affecting the interpretation of other phrases, only within its own domain. Three uncontroversial examples of scope affecting some aspect of the interpretation are: quantifier-quantifier, quantifier-pronoun, quantifier-negative polarity item.
In formal semantics, a generalized quantifier (GQ) is an expression that denotes a set of sets. This is the standard semantics assigned to quantified noun phrases . For example, the generalized quantifier every boy denotes the set of sets of which every boy is a member: { X ∣ ∀ x ( x is a boy → x ∈ X ) } {\displaystyle \{X\mid \forall x ...
Thus, the mass noun "water" is quantified as "20 litres of water" while the count noun "chair" is quantified as "20 chairs". However, both mass and count nouns can be quantified in relative terms without unit specification (e.g., "so much water", "so many chairs", though note the different quantifiers "much" and "many").
the universal quantifier ∀ and the existential quantifier ∃; A sequence of these symbols forms a sentence that belongs to the first-order theory of the reals if it is grammatically well formed, all its variables are properly quantified, and (when interpreted as a mathematical statement about the real numbers) it is a true statement.
WASHINGTON (Reuters) -The Justice Department late on Wednesday asked a U.S. appeals court to reject an emergency bid by TikTok to temporarily block a law that would require its Chinese parent ...
In generative grammar, the technical term operator denotes a type of expression that enters into an a-bar movement dependency. [1] [2] [3] One often says that the operator "binds a variable".
