Interrogative Adjectives | (Easy Definition & Examples 2025)

What are Interrogative Adjectives?

Interrogative Adjectives are used to describe a noun that is used in an interrogative sentence. It is also called Interrogative Determiners. It is one of the types of Adjectives.

In other words, it is used to describe a noun by asking a question. These adjectives are usually located before the noun in the sentence.

Some examples of Interrogative Adjectives are,

• which
• whose
• what
• how
• which
• where

But mostly considered adjectives are of three. Those are which, what and whose.

Now, let us learn when we have to use Interrogative Adjective in a sentence.

Usage of Interrogative Adjectives

The adjectives what and which is often can be used reciprocally (interchangeably) depending on the situation and the adjective (whose) is quite different from these two.

1) What

The adjective (what) is used in the question when the options (guess or answers) are unlimited or not known.

For example: What cars do you like the most?

2) Which

The adjective (which) is used in the question when the options (guess or answers) are limited.

For example: Which bike did you like the most?

Difference between What and Which

1) Let us understand the difference with a common example.

• “What present do you think you’ll get for birthday?
• “Which present do you think you’ll get for birthday?

In the first example, we can observe that the person doesn’t have any idea or guess about the present because it can be anything (unlimited possibilities). So, for this kind of situation, the adjective (what) is used.

But, in the second example, the person can guess and may have an idea about the present because it is limited. So, for this kind of situation, the adjective (which) is used.

2) Let us consider another similar example.

• “What dress do you want to wear for birthday party?”
• “Which dress do you want to wear for birthday party?”

In the first sentence, “what” is used for many options (unlimited) – it can be any type of dress (asking in general).

In the second example, “which” is used for limited options – it can be from the specific dresses (asking in specific).

3) Another similar example is given below to understand this concept well.

• “What help do you need?”
• “Which help do you need?”

Here, in the first example, the person won’t know what help he does and it can be any type of help and in the second example, the person is aware that he/she is offering help from what they know (expect).

3) Whose

The adjective (whose) is used in the question to determine the ownership of the thing (belongings), etc.

For example: May I know whose painting is this?

Interrogative Adjective Examples

Below are a few easy examples given for each adjective.

• What song do you want to listen to?

Sentence Structure: What (IA) + song (Subject) + do (Verb) + you want to listen to (Object)?

Here, the adjective (what) is used to ask from the unlimited choices of songs. This adjective is used before the noun (song).

• Which book do you recommend for spirituality?

Sentence Structure: Which (IA) + book (Subject) + do you recommend (Verb) + for spirituality? (Object)

In the above example, the adjective “which” is used to ask from the limited choices of books. The noun mentioned here is “book”.

• Whose hat is this?

Sentence Structure: Whose (IA) + hat (Subject) + is (Verb) + this? (Object)

Interrogative Adjective in Indirect Questions

Let us look at few examples.

• She asked what dress should she wear for the party.

• I was told not do take the job which I hate doing it.

A common mistake while using Interrogative Adjectives

Mistake 1: People often make mistakes while using “who’s” instead of “whose”. Who’s is the short abbreviation for “who is” and whose is used for determining the ownership of a thing, etc. So, both are different from each other.

Let us take an example.

• Incorrect: Who’s car is this?
• Correct: Whose car is this?
