What is Quantifier:
A quantifier is a linguistic component used to generate a quantification—a construct that specifies the number of specimens in a specific domain of discourse that satisfy a given open formula. Quantifiers are used in logic. Discrete mathematics, natural languages, and logic all frequently use quantifiers.
