What are interrogative adverbs? They are; why, where, when, and how. We use these words/interrogative adverbs to ask questions. When we use these adverbs to make questions, we must invert the subject with the auxiliary verb. So; ‘why can you’ and NOT ‘why you can’.
Why: we use ‘why’ to acquire a reason for something;
- Why are you late today?
- Why does David always ask just boring questions?
- Why can’t we go to the beach this Saturday dad?
Note that, in all these examples the order is ‘interrogative adverb-auxiliary verb-subject’, as is the correct order for asking questions regardless of the adverb.
Where: We use the interrogative adverb ‘where’ to talk ask about a place;
- Where does Gemma live?
- Where do we have to go tonight?
- Where is the shop that you spoke to me about?
When: we use the interrogative adverb ‘when’ in reference to time.
- When must we leave home?
- When should they advise us of the problem?
- When can I see you next?
How; we use the interrogative adverb ‘how’ to talk about the manner, degree, time, amount, or quantity in which something is done.
- How did you know what he was talking about?
- How can you show me the directions?
- How does Jeremy know about our secret?
- How much electricity de he use up?
- How many drinks would you like?
In all the above examples we have examples of ‘how’ with; manner, degree, time, amount and quantity.
