WHAT DOES EXISTENTIAL QUANTIFIER MEAN IN ENGLISH?
Existential quantification
In predicate logic, an
existential quantification is a type of quantifier, a logical constant which is interpreted as "there exists," "there is at least one," or "for some." It expresses that a propositional function can be satisfied by at least one member of a domain of discourse. In other terms, it is the predication of a property or relation to at least one member of the domain. It asserts that a predicate within the scope of an existential quantifier is true of at least one value of a predicate variable. It is usually denoted by the turned E (∃) logical operator symbol, which, when used together with a predicate variable, is called an
existential quantifier ("∃x" or "∃(x)"). Existential quantification is distinct from
universal quantification ("for all"), which asserts that the property or relation holds for
all members of the domain. Symbols are encoded U+2203 ∃ there exists (HTML: ∃ ∃ as a mathematical symbol) and U+2204 ∄ there does not exist (HTML: ∄).
Definition of existential quantifier in the English dictionary
The definition of existential quantifier in the dictionary is a formal device, for which the conventional symbol is ∃, which indicates that the open sentence that follows is true of at least one member of the relevant universe of interpretation, as Fx meaning "something is F," "something Fs," or "there are Fs.".
