Determiners

Determiners are words that introduce nouns and answer questions like "which one?", "how many?", or "whose?" They sit before the noun — and before any adjectives — and they are grammatically required in many positions where some languages would use nothing at all. Articles (a, an, the) are the most common determiners, but the category is much broader than that.

The main types of determiner are: articles (a, an, the), demonstratives (this, that, these, those), possessive determiners (my, your, his, her, its, our, their), quantifiers (some, any, many, much, few, several, all, both, each, every), interrogative determiners (which, what, whose), and distributives (each, every, either, neither). Numbers — both cardinal (three books) and ordinal (the first chapter) — also function as determiners.

A small distinction in form can produce a large shift in meaning, especially with quantifiers. Compare a few and few: A few people attended has a positive flavour — some people came, which is more than none. Few people attended is negative — hardly anyone came, and the speaker is disappointed. The same pattern applies to a little (some, enough) versus little (not enough): I have a little money (I can manage) versus I have little money (I am in trouble).

Determiners rarely stack. You cannot say the my book or a this pen — English allows only one central determiner per noun phrase. There is a class of pre-determiners that can appear before the main determiner: all the students, both my parents, half an hour, such a pity, double the price. These pre-determiners — all, both, half, double, such, what — are the exception to the one-determiner rule.

Learners should note that some determiners work only with countable nouns (many, few, several), some only with uncountable nouns (much, little), and some with both (some, any, all, most). Getting this right is a matter of learning which nouns are countable and which are not — a broader topic, but one that determines determiner choice at every turn.

The relationship between determiners and pronouns is worth noting: many determiner forms have a corresponding pronoun form. This pen is mine uses a demonstrative determiner (this) and a possessive pronoun (mine). That is hers uses a demonstrative pronoun (that) and a possessive pronoun (hers). The determiner version always modifies a noun; the pronoun version stands alone.
