Words that introduce nouns and tell us which one, how many, or whose
A determiner is a word placed before a noun to introduce it. Determiners tell us which one, how many, or whose the noun is. They always come at the beginning of a noun phrase.
Every determiner belongs to one of these seven types:
Articles are the most common determiners. They tell us whether we are talking about something specific (the) or general (a / an).
| Article | Type | Used Before | Examples |
|---|---|---|---|
| a | Indefinite | Singular nouns beginning with a consonant sound | a dog, a car, a university* |
| an | Indefinite | Singular nouns beginning with a vowel sound | an apple, an hour*, an egg |
| the | Definite | Any noun when both speaker and listener know which one | the sun, the book I gave you |
Use "a" or "an" based on the sound of the next word — not its spelling.
"a university" ✔ (starts with yoo sound) | "an hour" ✔ (starts with ow sound — h is silent)
Demonstrative determiners point to specific nouns and tell us whether they are near or far, and whether they are singular or plural.
| Determiner | Number | Distance | Example |
|---|---|---|---|
| this | Singular | Near (close to speaker) | This book is mine. |
| that | Singular | Far (away from speaker) | That building is tall. |
| these | Plural | Near (close to speaker) | These mangoes are sweet. |
| those | Plural | Far (away from speaker) | Those birds are eagles. |
Think of it as pointing: this/these = you can touch it right now. that/those = it's at a distance. Singular needs is; plural needs are.
Possessive determiners show ownership or belonging. They answer the question: "Whose?"
| Person | Determiner | Example |
|---|---|---|
| 1st person singular | my | my bag, my friend |
| 2nd person | your | your book, your idea |
| 3rd person singular (male) | his | his car, his name |
| 3rd person singular (female) | her | her dress, her smile |
| 3rd person singular (thing/animal) | its | its tail, its colour |
| 1st person plural | our | our school, our team |
| 3rd person plural | their | their house, their plan |
its = possessive determiner → The cat licked its paw.
it's = short for "it is" → It's a lovely day.
If you can replace it with "it is" — use it's. If not — use its.
Quantifiers tell us about the quantity (how much / how many) of a noun. Some quantifiers are used with countable nouns, some with uncountable nouns, and some with both.
| Quantifier | Used with | Example |
|---|---|---|
| many | Countable nouns only | many books, many students |
| few / a few | Countable nouns only | few apples, a few friends |
| much | Uncountable nouns only | much water, much time |
| little / a little | Uncountable nouns only | little milk, a little sugar |
| some | Both (positive sentences) | some rice, some books |
| any | Both (questions & negatives) | any milk? / no any books |
| all | Both | all students, all water |
| enough | Both | enough time, enough chairs |
| several | Countable nouns only | several reasons, several days |
| no | Both | no money, no students |
few / little (without "a") = negative meaning → almost none, not enough
→ She has few friends. (unfortunately not many)
a few / a little (with "a") = positive meaning → some, not many but enough
→ She has a few friends. (she has some, which is good)
Numeral determiners tell us the exact number of something. They are of two types: Cardinal and Ordinal.
| Type | Answers | Examples |
|---|---|---|
| Cardinal Numerals | How many? (exact count) | one, two, three, ten, hundred… I have three pencils. |
| Ordinal Numerals | In what order / position? | first, second, third, last, next… She came first in the race. |
Distributive determiners refer to individual members of a group, treating them one by one or as two alternatives. They are: each, every, either, neither.
| Determiner | Meaning | Noun | Verb | Example |
|---|---|---|---|---|
| each | Every one individually (from 2 or more) | Singular | Singular | Each student has a book. |
| every | All members without exception (3 or more) | Singular | Singular | Every child needs love. |
| either | One or the other (of two) | Singular | Singular | Either road leads to town. |
| neither | Not one nor the other (of two) | Singular | Singular | Neither answer is correct. |
All four distributive determiners take a singular noun and a singular verb.
✔ Each student has | ✔ Every player is
✘ Each students have (wrong!)
Interrogative determiners are used to ask questions about nouns. They are: which, what, whose.
| Determiner | Used to ask about | Example |
|---|---|---|
| which | Choice from a limited, known set | Which book do you want? |
| what | Open question — no specific set | What colour is your bag? |
| whose | Ownership / possession | Whose pen is this? |
These are the mistakes students make most often — study them carefully!
Choose from: the / a / an / some / every / this / their / few / which / both
