Grammar explanation
To make questions, we often put the verb before the subject. This is called inversion.
| Affirmative | Question |
| I am late. | Am I late? |
| I can help. | Can I help? |
| She is sleeping. | Is she sleeping? |
| We have met before. | Have we met before? |
If there is a question word (why, what, where, how, etc.), it goes before the verb.
| Question | Question with question word |
| Are you late? | Why are you late? |
| Was she there? | When was she there? |
| Can I help? | How can I help? |
| Have we met before? | Where have we met before? |
This is true for sentences with be, sentences that have auxiliary verbs (e.g. They are waiting. She has finished.) and sentences with modal verbs (can, will, should, might, etc.).
Questions in the present simple and past simple
For other verbs in the present simple, we use the auxiliary verb do/does in the question.
| Affirmative | Question | Question with question word |
| You work at home. | Do you work at home? | Where do you work? |
| It costs £10. | Does it cost £10? | How much does it cost? |
We use the auxiliary verb did in the past simple.
| Affirmative | Question | Question with question word |
| She went home. | Did she go home? | Where did she go? |
| They went to the cinema. | Did they go to the cinema? | Where did they go? |
Subject questions
In some questions, who or what is the subject of the verb. There is no inversion of subject and verb in these questions.
Who broke the window?
Who is knocking on the door?

Hello sribashu30,
Both are correct. When word is repeated like the indefinite article in this sentence you can often omit it.

Hello Oumou,
I've had a quick glance and what you wrote looks correct to me and seems to be what is taught on this page. Do you see a discrepancy between your formulas and what is on this page?
All the best,

Hello Allate,
Those questions are perfectly fine.

Hello EnglishIsChildsPlay,
In modern English whom is very rare and is used mainly when it directly follows a preposition (when who cannot be used). This is also true in question forms:
The equivalent question using who would put the preposition at the end:
