What are Adjectives of Number?
Adjectives of Number are words that tell us how many people or things we are talking about. These adjectives help us understand quantity in numbers—whether it’s exact or not-so-exact.
In short:
They answer the question: “How many?” or “In what order?”
Two Main Types of Number Adjectives
We won’t throw math at you (you’re safe here), but we do need to look at two kinds of number adjectives:
1. Definite Numeral Adjectives
These adjectives give a clear number or position. No guessing here! We know exactly how many or in what order.
Types of Definite Adjectives:
- Cardinal Numbers – 1, 2, 3, 4… (One apple, three dogs)
- Ordinal Numbers – 1st, 2nd, 3rd… (First prize, second round)
- Multiplicative Numbers – double, triple, quadruple if you’re feeling fancy
Common Definite Adjectives:
One, Two, First, Second, Third, Double, Triple
Examples:
- She has two cats that act like they own the house.
- This is my first time baking… and possibly the last.
- He gave me a double portion of fries – now that’s true love.
2. Indefinite Numeral Adjectives
These adjectives do not tell the exact number. They’re used when we don’t know or don’t care to say the exact count.
Common Indefinite Adjectives:
- Some
- Many
- Few
- Several
- All
- Any
Examples:
- I invited some friends, but only the hungry ones showed up.
- Many people tried the new café – half of them stayed for the Wi-Fi.
- He gave few answers during the exam. Mostly wrong ones.

Usage in Different Contexts
Adjectives of Number are used in different ways depending on the context. Let’s see:
In counting (Cardinal)
- She has three pencils.
In order/position (Ordinal)
- He stood second in line.
To show repetition (Multiplicative)
- He gave me a double gift!
When the number is not clear
- Several people were present.
Definite vs Indefinite Adjectives
Type | Definition | Example |
---|---|---|
Definite | Shows exact number or order | I have three siblings. |
Indefinite | Shows uncertain or unspecific number | Many people like ice cream. |
