What is an indefinite adjective in English?
An indefinite adjective is a word that comes before a noun and modifies it. It modifies the noun in a non-specific way, meaning it does not refer to a definite or specific number.
A list of indefinite adjectives in English:
- Some
- Many
- Plenty of
- Much
- More
- Less
- A lot of
- A few/the few
- Several
- Enough
- Other
- Little/a little/the little
Some people from an NGO came to meet you at the office.
In the example, the word ‘some’ works as an indefinite adjective as it modifies the noun ‘people’. It refers to an indefinite quantity of the noun. The quantity it refers to is considered good.
I have been to many countries, but the diversity that we see in India is unparalleled.
The word, in this example, modifies the noun ‘countries‘ by defining it with an uncertain quantity. The word ‘many’ refers to a large number of something.

Indefinite adjective vs indefinite pronoun
Most of the words in the list above can function as both an adjective and a pronoun. As a pronoun, they don’t take a noun after them and stand alone.
- I bought a lot of new pants last month for charity. I still have some with me. (indefinite pronoun)
- We are looking for some writers. (indefinite adjective)
- Thousands of people joined the protest in the morning at the TED Mall. Many of them are still there. (indefinite pronoun)
- I gave him many ideas to get rich. (indefinite adjective)
- There were over 200 guests. Several of them are still in the hall.
- Several people were fired last month.
- You can eat this. I have more.
- Give me more water.
Notice that when these words function as an adjective, they have a noun after them that they modify. And when they function as a pronoun, they refer to a noun and stand alone. The nouns that the indefinite adjectives modify in these examples are underlined.
Not all indefinite pronouns can function as indefinite adjectives
- Someone
- Something
- Anyone
- Anything
- Everyone
- Everything
- No-one
- Nothing
Examples:
- Someone came to see you at the office an hour ago.
- I have everything that I need.
- Nothing is impossible.
These are words that function as indefinite pronouns; they don’t function as adjectives. Don’t consider them an indefinite adjective.
