Quantifiers are determiners used to express the quantity of the noun being described. Like possessive adjectives, quantifiers usually precede all other elements in a noun phrase. Some common quantifiers are most, much, any, no, some, and few.

Choose a quantifier that is appropriate for your noun. Some quantifiers can be used with all types of nouns, some can be used only with countable nouns, and others can be used only with uncountable nouns.
Check your subject-verb agreement carefully when you use a quantifier. Some quantifiers have special rules for subject-verb agreement.
In general, do not use articles before quantifiers.
