What is a determiner in English?

A determiner is the word in front of a noun that tells you which one, whose, or how many: the colander, my larder, that jar, some nutmeg, three ramekins, which shelf. Articles, demonstratives, possessives, quantifiers, numbers, and interrogatives are all determiners. They occupy one central slot, which is why the my colander is impossible.

Can I use two determiners together?

Not two central ones. The, a, this, my, some, and which cannot share the slot. You can put a predeterminer in front of a central one (all the oranges, both these jars) or an adjective after the determiner (the heavy colander). The test is whether both words are trying to point rather than describe.

What is the difference between a determiner and an adjective?

A determiner points (which, whose, how many) and takes the first seat. An adjective describes (heavy, copper, Seville, warm) and sits after that seat. You can stack adjectives (the heavy copper colander) but you cannot stack central determiners (the my colander). Some and fresh in some fresh nutmeg show the order: determiner, then adjective, then noun.

Yes. The, a, and an are articles, and articles are a kind of determiner. They fill the same slot as this, my, and some, which is why the my colander and this the jar do not work. A page on the covers when to use it and when to leave the slot empty; this page is about the slot itself.

When do I leave the determiner slot empty?

With plural and uncountable nouns used in a general sense: Marmalade keeps. Jars must be warm. That empty slot is a choice, sometimes called the zero article. As soon as you mean a particular set, the determiner comes back: the marmalade in this pan, these jars, my recipe.

Determiners: The Slot Before a Noun

Written by Eleanor Whitfield, Lead English Curriculum Editor · Reviewed September 2026

A determiner is the small word that sits at the front of a noun and tells you which, whose, or how many: the colander, my larder, that jar, some nutmeg, three ramekins, which shelf. English allows one central determiner on a noun. You can say the colander or my colander, not the my colander. Articles, demonstratives, possessives, quantifiers, numbers, and interrogatives all compete for that same slot.

That colander in my larder is the one I use for the marmalade oranges.

that, my, and the each fill the determiner slot for a different noun

What it is

A noun rarely walks into an English sentence alone. Something in front of it answers which one, whose, or how many, and that something is a determiner. The, a, and an are determiners. So are this, that, these, those; my, your, his, her, its, our, their; some, any, no, each, every, much, many, few, little; one, two, three; and which, what, whose in questions. They all want the same seat. Adjectives sit after that seat (the heavy colander), which is why you can stack adjectives but you cannot stack central determiners.

The heavy colander (the = determiner, heavy = adjective). My three ramekins (my = determiner, three = a number in the same family). The my colander is impossible because two central determiners are fighting for one slot.

How to spot it

Find the noun and look immediately left, skipping adjectives. The word that tells you which or how many is the determiner. If nothing is there (marmalade stains cloth), you have a zero article, which is also a determiner choice, used with general plurals and uncountables.

the marmalade (article: a definite jar or batch)
that nutmeg grater (demonstrative: the one I am pointing at)
her larder (possessive: whose larder)
some rind, three ramekins, which shelf (quantifier, number, and interrogative)

Some words are determiners in front of a noun and pronouns when they stand alone: this colander versus this is mine; some rind versus I want some. The job changes; the form often does not.

Determiners Quick Reference

The main kinds of determiner

Kind	Forms	Example
Articles	the, a, an, and no article	the colander, a ramekin, marmalade (in general)
Demonstratives	this, that, these, those	this jar, those oranges
Possessives	my, your, his, her, its, our, their	my larder, their recipe
Quantifiers	some, any, no, each, every, much, many, few, little, enough, all	some nutmeg, each orange
Numbers	one, two, three, first, second	three ramekins, the first batch
Interrogatives	which, what, whose	which shelf, whose grater

Common Determiners Examples in English

The determiner slot doing its six everyday jobs, one kind at a time:

Articles

Pass me the colander.: the: we both know which one
I need a ramekin for the extra zest.: a: one of many, first mention
Marmalade keeps for months in a cool larder.: no article: marmalade in general
An orange this size needs more sugar.: an before a vowel sound

The, a/an, and no article are the choice you make on almost every noun. Other determiner pages go deeper; here they are just three occupants of the same slot.

Demonstratives and Possessives

This grater is sharper than that one.: this near, that further away
These jars are ready; those oranges still need peeling.: these and those as plurals of this and that
My larder is colder than her pantry.: my and her: whose, not which
Their recipe uses Seville oranges only.: their plus noun; not theirs recipe

Possessive determiners (my, her, their) go in front of the noun. Possessive pronouns (mine, hers, theirs) replace the noun: this grater is mine.

Quantifiers and Numbers

Some nutmeg goes a long way.: some with an uncountable noun
There aren't many Seville oranges left.: many with a plural countable
Each orange is scored before it goes in the pan.: each plus a singular noun
Three ramekins of zest should be enough.: a number filling the determiner slot

Much and little go with uncountables (much sugar, little rind). Many and few go with plurals (many oranges, few jars). A number is a determiner too: three ramekins, not the three my ramekins.

Interrogatives and the Empty Slot

Which shelf holds the sealed jars?: which plus noun: a choice from a known set
What sugar do you use for the second boil?: what plus noun: a more open question
Whose grater is on the draining board?: whose plus noun: asking about the owner
Jars must be warm before you fill them.: no article: jars as a class, a general instruction

Which, what, and whose fill the determiner slot in questions, so they do not combine with the or my: which the shelf is impossible.

How Determiners Work

One central slot, several kinds of word that can fill it, and a few that sit in front of it.

One Central Determiner per Noun

The, a, this, my, some, each, and which all want the same seat. English will not let two of them sit there together. The my colander, this the jar, and my some nutmeg are all impossible. Choose one: the colander, my colander, this colander, some nutmeg.

My colander is in the sink. This colander is in the sink.

my or this, never both in front of colander

Pick one: the, this, my, some, each.

Adjectives Come After the Determiner

Once the slot is filled, adjectives can stack: the heavy copper colander, my three small ramekins. The determiner stays first. That is the practical difference between a determiner and an adjective: heavy describes, the points; heavy can join another adjective, the cannot join my.

the heavy copper colander

the first, then adjectives, then the noun

Determiner, then adjective, then noun.

The Empty Slot Is Still a Choice

Plural and uncountable nouns used in a general sense take no article: Marmalade keeps. Jars must be warm. That empty slot is a determiner choice, not a missing word. Add the the moment you narrow the noun down: the marmalade in this pan, the jars on the top shelf.

Marmalade keeps. The marmalade in this pan is still hot.

general: no article; narrowed: the

General plural or uncountable = nothing.

Some Determiners Stand Alone as Pronouns

This, that, these, those, some, any, each, enough, mine, and yours can drop the noun when it is already clear: I want some. This is sharper. Each is scored. In that job they are pronouns, not determiners. The form is often the same; the presence or absence of a following noun is what changes the label.

Those jars are ready. Those are ready.

those plus noun: determiner; those alone: pronoun

With a noun = determiner. Alone = pronoun.

Numbers Share the Slot, Ordinals Often Sit with The

Cardinal numbers (one, two, three) fill the determiner slot: three ramekins, not the my three as two centrals. Ordinals (first, second, next, last) usually combine with the because they pick out a unique position: the first batch, the last orange. All the oranges is different again: all is a predeterminer, sitting in front of the.

Three ramekins. The first batch. All the oranges.

number as determiner; ordinal with the; all in front of the

Numbers fill the slot; all the is two slots.

Common Mistakes with Determiners

Incorrect: The my colander is in the sink.

Correct: My colander is in the sink.

The and my are both central determiners, and a noun has room for only one. Choose my colander or the colander, not both.

Incorrect: I like the marmalade in general.

Correct: I like marmalade.

A general uncountable takes no article. The marmalade would mean a particular batch you and the listener can identify.

Incorrect: These my jars are ready.

Correct: These jars are ready. / My jars are ready.

These and my both want the central slot. You can say all my jars (all is a predeterminer) but not these my jars.

Incorrect: Both them need new lids.

Correct: Both of them need new lids.

Both in front of a pronoun needs of. Both these jars (both plus determiner plus noun) is fine without of, though both of these jars is also correct.

Predeterminers: All, Both, and Half

A few words sit in front of the central determiner rather than in it.

All, both, half + the / this / my

All, both, and half can stand in front of another determiner: all the oranges, both these jars, half my sugar. They do not replace the; they add to it.

All the oranges are Seville.: all in front of the
Both these jars need new lids.: both in front of these
Half my sugar went on the first boil.: half in front of my

All oranges (no the) is a general statement. All the oranges points at a known set. Both needs a plural of two: both jars, both of them.

All of, both of, half of

The same words take of before a pronoun, and often before a determiner in careful speech.

All of them are Seville.: of before a pronoun is required
Both of these jars need new lids.: of optional before a determiner
Half of the sugar went on the first boil.: half of plus determiner plus noun

All them and both them are errors. Once a pronoun follows, of has to be there.
