Determiners
Determiners are words placed before nouns to show which one, how many, or whose it is. They are one of the most essential — and most varied — word classes in English.
What is a determiner?
A determiner is a word that introduces a noun and specifies its reference — whether it is specific or general, how many there are, or who it belongs to. Every determiner appears before any adjectives that modify the noun.
The dog is friendly. · My sister lives in Paris. · Some students arrived late.
Each child received a prize. · Both answers are correct.
Types of determiners
| Type | Examples | Use |
|---|---|---|
| Articles | a, an, the | Introduce nouns as specific or general |
| Demonstrative | this, that, these, those | Point to specific nouns by distance |
| Possessive | my, your, his, her, its, our, their | Show ownership |
| Quantifier | some, any, many, much, few, little, all, both | Express amount or quantity |
| Numeral | one, two, first, second, last | Express exact number or order |
| Distributive | each, every, either, neither | Refer to members individually or in pairs |
| Interrogative | which, what, whose | Ask about identity or possession |
Determiners vs. pronouns
Many determiner words — this, that, my, some, which — can also be used as pronouns. The key difference: a determiner always appears directly before a noun; a pronoun stands alone in place of a noun.
| As a determiner (before noun) | As a pronoun (stands alone) |
|---|---|
| This book is great. | This is great. |
| My car broke down. | The car is mine. |
| Some people disagreed. | Some disagreed. |
| Which route is fastest? | Which is fastest? |
Distributive determiners: each, every, either, neither
- each — refers to individual members one at a time: Each student has a textbook. Always singular.
- every — refers to all members as a whole: Every student passed. Always singular.
- either — one of exactly two options: Either answer is acceptable.
- neither — not one of two: Neither option is ideal.
Each child was given a different gift. (one by one — individually)
Every child enjoyed the party. (all — as a whole group)
Pre-determiners
A small set of words can appear before a determiner. These are called pre-determiners: all, both, half, double, twice, such, what (in exclamations).
All the students passed. (all + the + noun)
Both my sisters are doctors. (both + my + noun)
Half the class was absent. (half + the + noun)
What a beautiful day! (what + a + noun)
Only one determiner at a time: You cannot use two determiners of the same category before one noun. Never say the my book or this some water. Choose one: the book or my book.
Tip: The order before a noun is always: pre-determiner → determiner → adjective(s) → noun. For example: All her beautiful old paintings — all (pre-det) + her (det) + beautiful old (adjectives) + paintings (noun).
