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 Sir could you please explain to me why I shouldn't use "what did happen next?" And why the right form is " what happened next?" ( affirmative and whats the meaning of affirmative) And also in what conditions I should do the same, I mean I thought happen also needs auxiliary verb... I'm confused, the example was from speak out upper intermediate second edition book page 128 GRAMMAR


Hello anahitabehzadi,

We can ask questions about different parts of a sentence. For example:

The boy broke the window.

In this sentence we have a subject (the boy) and an an object (the window). When we ask about the object we use an auxiliary verb:

What did the boy break?

However, when we ask about the subject we simply replace 'the boy' with a question word:

Who broke the window?

Your example is similar to this so no auxiliary is needed.


These are called 'object questions' and 'subject questions'. You can read a little about them here:

Dear Sir, Could you tell me why in this sentence: Across a river swam people simply the subject's and a verb's place are changed but in this sentence: Only then did I understand my mistake is an auxiliary verb used? When is the inversion supposed to be done by changing places and when by using an auxiliary verb? Thank you in advance.

Hi Zuzanna,

These examples are actually two different types of inversion.

The first one (Across a river swam people) is subject-verb inversion. No auxiliary is added. This is done for a few particular purposes. One purpose is to emphasise the movement of something, and that is the reason for inversion in this example. Other purposes are to emphasise the location of something (e.g. In the room stood a grand piano) and to report a quotation (e.g. "Where's the station?" asked Diana). 

Your second example is subject-auxiliary inversion. An auxiliary verb needs to be added, if it is not already present. This is done when the sentence begins with a negative or limiting adverbial (Never had I met ... Little did I know ... Rarely did I go there ... etc.). It can also be used in conditional sentences (e.g. Had I not left early, I would have missed the train. = If I hadn't left early, I would have missed the train.)

Does that make sense? I hope it helps.

Nice explanation, but the amount of different verb tenses in this topic only makes ESL students confused. I'd argue it's better to divide it into smaller topics, like "Questions with 'to be' " and "Questions with auxiliar verb 'do' " etc

When I use verb to be and when I use auxiliary verb in wh question???

Hi Hala jabir,

Use the verb "to be":
- if "be" is the main verb (e.g. How are you? Which station is closest?)
- with present continuous or past continuous (e.g. Where are you going? What were you doing?)
- with passive voice (e.g. Where was the movie filmed?)

Use "do / does / did":
- with verbs (apart from "be") in the present simple or past simple (e.g. Where do you live? Where does he live? Why did she go to London?)

Use "have / has / had":
- with verbs in the present perfect or past perfect (e.g. Where have you been? Where has she been? When I came home, why had you already eaten?)

I hope that helps :)

Hi LearnEnglish Team, My question has to do with the proper ending punctuation in the following context: If a compound sentence contains two clauses, one of which is a statement and the other a question, how should one punctuate it? For example, which of the following is correctly punctuated? Can you give us your order number and we will check on it. Can you give us your order number and we will check on it? We could, of course, avoid the issue by simply rewriting the sentence, as in this example: If you can give us your order number, we will check on it. But rather than rewrite the sentence to avoid the issue, I’m curious how you would advise punctuating the sentence in its original construction. Thanks for your help. Tim O'Brien

Hello Tim O'Brien,

First of all, I would be tempted to rewrite the sentence! It reads to me more like a spoken sentence than typical written language. I would most likely use a conditional form (If you can... then we will...).


That said, I think I would probably use a question mark as the primary function of the sentence is requesting. It is a debatable point, however, so the safest course would be to consult the style guide for your organisation, or else a standard style guide if your organisation does not have one. The Chicago Manual of Style is the most popular in the US, I believe.
