English needs a helping verb to ask a present simple question, and choosing between do and does is where the -s goes. This lesson covers question order, negatives with don't and doesn't, and the short answers conversation runs on.
English cannot ask a present simple question by changing the order of the words it already has. You like coffee cannot become Like you coffee — that pattern died out around Shakespeare's time and survives only in fixed phrases. What English does instead is borrow an auxiliary verb, do, purely to carry the question. It adds no meaning of its own; it exists to occupy the position at the front of the sentence.
The same auxiliary handles negatives. I don't smoke and Does she work here are the same piece of machinery pointed in two directions, which is why the two are best learned together rather than in separate lessons. Once you can produce both, present simple conversation becomes available to you, because almost every question you will be asked in a first conversation uses this pattern.
One detail causes more errors than everything else here combined: the third-person -s. English allows only one verb per clause to carry it, and when does appears, does has taken it. Does she like coffee is correct; Does she likes coffee puts the -s on twice. Learners typically know this rule and still break it under time pressure, which means it needs drilling rather than explaining.
How to form Questions with Do and Does
| Subject | Question | Negative | Short answer |
|---|---|---|---|
| I / you / we / they | Do you work here? | I don't work here. | Yes, I do. / No, I don't. |
| he / she / it | Does he work here? | He doesn't work here. | Yes, he does. / No, he doesn't. |
| with a question word | Where do they live? | — | — |
| with a question word | What does she do? | — | — |
| subject questions | Who lives here? | — | (no do at all) |
| the verb be | Are you a student? | I'm not a student. | Yes, I am. / No, I'm not. |
Questions with Do and Does: the key rules
-
Present simple questions need do or does at the front — do for I/you/we/they, does for he/she/it.
Do you work here? Does she live in Rome?
-
After do or does the main verb goes back to its base form; the -s moves onto does.
Does he play tennis? — not 'Does he plays tennis?'
-
Negatives follow the same pattern with don't and doesn't.
I don't smoke. He doesn't eat meat.
-
Short answers repeat the auxiliary, not the main verb.
Do you like it? — Yes, I do. / No, I don't.
-
The verb be needs no do at all: it makes its own questions.
Are you tired? — not 'Do you be tired?'
When to use Questions with Do and Does
-
Yes / no questions
The auxiliary goes first, then the subject, then the base verb. The answer is expected to be yes or no.
Do you speak French? Does the shop open on Sunday?
-
Wh- questions
The question word comes before the auxiliary. Everything else stays in the same order.
Where do you work? What does this word mean?
-
Negative statements
Don't and doesn't come before the base verb. This is the same auxiliary doing a different job.
They don't live here any more. He doesn't drink alcohol.
-
Short answers
English answers with the auxiliary, not with the main verb. Repeating the main verb sounds incomplete.
Do you smoke? — No, I don't. Does she drive? — Yes, she does.
-
Negative questions
Used to express surprise or to check something you assumed was true.
Don't you like it? Doesn't he work on Fridays?
-
Emphatic do
The same auxiliary in a positive statement adds emphasis or contradicts someone.
I do like it — I'm just tired. She does know the answer.
When you need do, and when you must not use it
Do is only needed when the sentence has no auxiliary of its own. Adding it to a sentence that already has one is the second most common error in this topic.
Needs do / does
Ordinary main verbs — work, live, like, want, go, have (as an activity). These have no auxiliary, so one must be borrowed.
Do you live here? Does she want tea?
Never takes do
Be, can, will, would and the other modals are already auxiliaries. They ask questions by moving to the front themselves.
Are you ready? Can he swim? — not 'Do you are ready?'
Questions with Do and Does in example sentences
- Do you have any brothers or sisters?Standard yes/no question with do.
- Does your sister live in the city centre?Third-person subject, so does, and live loses its -s.
- What time does the film start?Question word, then does, then the base verb.
- I don't understand this word.The same auxiliary in a negative statement.
- She doesn't eat meat, but she eats fish.doesn't eat in the negative, eats with the -s in the positive.
- Do they know about the meeting? — Yes, they do.The short answer repeats the auxiliary, never the main verb.
- Who wants another coffee?A question about the subject needs no do at all.
- Doesn't he work at the hospital?Negative question, used to check something you thought was true.
Questions with Do and Does in a real conversation
Almost every question in a first conversation uses this one pattern. Count how many.
Ines:Do you live near here?
Bruno:Yes, I do — about ten minutes away. Do you?
Ines:No, I don't. I take the train. What do you do?
Bruno:I'm a nurse. My wife works here too — she doesn't start until ten.
Ines:Does she work in the same department?
Bruno:No, she doesn't. She's upstairs. Don't you know her?
Common mistakes (and how to fix them)
-
Does she likes coffee?
Does she like coffee?
Only one verb in the sentence carries the third-person -s, and does already has it.
-
You like pizza?
Do you like pizza?
Rising intonation alone is informal speech; written and standard spoken English needs the auxiliary.
-
Do you are a student?
Are you a student?
Be is its own auxiliary — adding do gives the sentence two.
-
Yes, I like.
Yes, I do.
The English short answer repeats the auxiliary. Repeating the main verb sounds unfinished.
Practise Questions with Do and Does today
This pattern is drilled, not understood. Say every sentence out loud, because the error appears under speed rather than on paper.
- Write ten yes/no questions you could ask a new colleague, five with do and five with does.
- Answer each one with a correct short answer, both positive and negative.
- Turn five positive statements about your routine into negatives with don't or doesn't.
- Write five wh- questions with what, where, when, why and how.
- Say aloud ten times: Does he like it? Does she work here? Does it cost much? — listening for the missing -s on the main verb.
Questions with Do and Does: frequently asked questions
When do I use do and when do I use does?
Does goes with he, she, it and any singular noun — does your brother, does the shop, does this train. Do goes with I, you, we, they and any plural noun. The rule is identical to the third-person -s on the main verb in a positive sentence, because it is the same -s: it simply moves onto the auxiliary once one is present.
Why is 'Does she likes coffee?' wrong?
Because the -s can only appear once per clause, and does has already used it. When the auxiliary takes the third-person marking, the main verb reverts to its base form: does she like. The same applies in the negative — she doesn't like, never she doesn't likes. If you can hear the -s on does, the main verb must be bare.
Can I ask a question without do, like 'You live here?'
In speech, yes — with rising intonation it is understood and used constantly between friends. In writing and in any formal or unfamiliar situation it sounds abrupt or non-native, and it is marked wrong in examinations. Learn the auxiliary version as your default and let the intonation-only version be something you recognise rather than produce.
Why do we say 'Are you a student?' and not 'Do you are a student?'
Because be is already an auxiliary verb and can move to the front by itself. Do exists to supply an auxiliary to sentences that lack one, so a sentence with be does not need it and cannot take it. The same applies to can, will, would, should and must: they all invert on their own.
Do I need do in questions about the subject?
No. When the question word is itself the subject — Who lives here? What happened? Which bus goes to the centre? — the word order is already statement order, so no auxiliary is required. Compare Who does she know, where who is the object and does is needed, with Who knows her, where who is the subject and it is not.
