✅ What Are Determiners?

Determiners are words that come before a noun.

They give more information about the noun.

They help answer questions like:

Which one?
Whose?
How many?

Without determiners, sentences can sound strange.

🧡 Example:
Wrong: “Student forgot book.”
Right: “The student forgot his book.”

“The” and “his” are determiners.
They make the meaning clear.

✅ Why Are Determiners Important?

They help you:

Talk about specific things
Show who something belongs to
Say how many things there are
Ask questions clearly

Using determiners correctly makes your English better!

🧱 Types of Determiners

Let’s look at the main types of determiners.

1. Articles: A, An, The

🔸 A / An – Indefinite Articles

We use a and an when we talk about something general or for the first time.

Use a before words that start with a consonant sound.
Use an before words that start with a vowel sound.

🧡 Examples:

I need a pen.
She bought an apple.
He is a doctor.
They live in an old house.

🔸 The – Definite Article

We use the when we talk about something specific or already known.

🧡 Examples:

Please close the door.
The book you gave me is great.
I’m going to the store.

2. Demonstrative Determiners: This, That, These, Those

They show where things are (near or far).

🔸 This / These → Things near you

This = 1 thing (singular)
These = more than 1 (plural)

🧡 Examples:

This pen is mine.
These cookies are yummy.
I like this song.

🔸 That / Those → Things far from you

That = 1 thing (singular)
Those = more than 1 (plural)

🧡 Examples:

3. Possessive Determiners: My, Your, His, Her, Its, Our, Their

They show ownership or belonging.
They answer: “Whose is it?”

Her dress is red.
The cat wagged its tail.
Our school is big.
Their house has a garden.

📝 Note:
Don’t mix up possessive determiners and pronouns.

Determiner: My book
Pronoun: The book is mine

4. Quantifying Determiners

They talk about how much or how many.
