What Are Interrogative Determiners?

We use interrogative determiners to ask questions. They make direct or indirect questions and exclamations.

English Interrogative Determiners

The three interrogative determiners in English are:

  1. what/whatever
  2. which/whichever
  3. whose/whosever

Interrogative Determiner: What

'What' is used in questions to ask for particular information about somebody or something. Unlike the pronoun 'what', which stands alone, the determiner 'what' always comes before a noun or a noun phrase.

What color is your eyes?

What kind of music do you like?

What time is it?


Notice that in the following examples, 'what' is a pronoun, not a determiner.

What do you do for a living?

What is your name?

Interrogative Determiner: Which

'Which' is used in questions to ask somebody to be exact about one or more people or things from a limited number.
That is why 'what' is considered a general determiner and 'which' is considered a specific determiner.

Which way is the pharmacy?

Which movie do you want to watch?

Which restaurant did you go to?

Now notice that in the following examples, 'which' is a pronoun, not a determiner.

Which do you prefer: chocolate or vanilla?

Which is better: Harry Potter books or movies?

Interrogative Determiner: Whose

'Whose' is used in questions to ask about what belongs to which person. Notice that 'whose' functions both as a possessive interrogative and determiner, so 'whose' is technically the only interrogative possessive determiner in English.

Whose jacket is this?

Whose house is up for sale?

Whose iPhone was stolen?


Now notice that in the following examples, 'whose' is a pronoun, not a determiner.

Whose are these shoes?

Whose is that limo outside?

Interrogative Determiners in Indirect Questions

Up till now, all the examples that we have seen so far are examples of direct questions. But, note that interrogative determiners can also appear in indirect questions. For example:

Can you tell me what flavor you want for your ice cream?

Do you know his sister is a teacher at which university?

I wonder whose house is up for sale.


Interrogative words are words that are used to ask questions to get different information. There are three main interrogative words that we discussed in the article. Now, let us have a quick look over them.
