Affirmative sentence + negative question tag
Why add a question tag
A question tag is a short question at the end of a statement. The speaker first expresses an idea and then invites the listener to confirm it.
The target pattern for this rule begins with an affirmative sentence and ends with a negative question tag. It is especially common in conversation when the speaker believes the information is true but wants to hear the other person's reaction.
In writing, put a comma before the tag and a question mark at the end.
affirmative statement, negative auxiliary verb + pronoun?
- verb / V —
- A word for an action or state, such as work or be. The pattern determines its form.
- auxiliary —
- A helping verb used to form tenses, questions or negatives: do, have, be.
- pronoun —
- A word used instead of naming a person or thing: I, you, she, it, they.
The room is ready, isn't it?
The room is ready, isn't it?
The speaker believes the room is ready and asks for confirmation; the affirmative is ready combines with the negative isn't it.
You work nearby, don't you?
You work nearby, don't you?
The main idea is affirmative; the short negative tag invites the listener to confirm it.
Polarity: affirmative → negative
First, check the main clause. If it contains no negation and states a fact, the target tag needs not.
In an ordinary question tag, the negative is usually contracted: is not → isn't, do not → don't, did not → didn't. In exercises requiring the exact form, use the standard contracted tag.
An affirmative main clause with an affirmative tag can also occur in English, but it conveys a different intention, such as surprise or genuine checking. This is a different grammatical pattern, not necessarily an error in itself.
affirmative clause → contracted negative question tag
- clause —
- A construction with a verb, often with its own subject: when I arrived. A non-finite clause may leave the subject unspoken: to get home.
Mira lives here, doesn't she?
Mira lives here, doesn't she?
Lives here is affirmative; doesn't she is the negative tag used to seek confirmation.
So you met Mira, did you?
So you met Mira, did you?
Both parts are affirmative; this is a possible different type of tag with a sense of new discovery, so it is not the target “affirmative → negative” pattern.
Be and an existing auxiliary verb
If the main clause already contains be, have as an auxiliary, or another auxiliary verb, use it in the tag. Change only the polarity: is → isn't, are → aren't, was → wasn't, have → haven't.
The tense in the tag must match the main clause. Do not combine was with isn't, or have finished with don't.
Do not copy the full predicate. The tag contains only the auxiliary verb and a short subject pronoun.
clause with be/have/an auxiliary, the same auxiliary + not + pronoun?
- clause —
- A construction with a verb, often with its own subject: when I arrived. A non-finite clause may leave the subject unspoken: to get home.
- auxiliary —
- A helping verb used to form tenses, questions or negatives: do, have, be.
- pronoun —
- A word used instead of naming a person or thing: I, you, she, it, they.
The shop was open, wasn't it?
The shop was open, wasn't it?
The past form was is repeated in the negative form wasn't; the shop is replaced with it.
They have finished, haven't they?
They have finished, haven't they?
Have is the auxiliary in the Present Perfect, so the tag repeats have rather than adding do.
Do, does, or did when there is no auxiliary
In an affirmative Present Simple sentence with an ordinary verb, there is no separate auxiliary. Build the tag with don't or doesn't.
Use doesn't with he, she, it, and the corresponding singular noun; use don't with I, you, we, they, and plural nouns. Do not repeat the main verb.
In an affirmative Past Simple sentence with an ordinary verb, use didn't for all persons. The form arrived or called in the main clause indicates the past tense.
Present Simple: don’t/doesn’t + pronoun?; Past Simple: didn’t + pronoun?
- pronoun —
- A word used instead of naming a person or thing: I, you, she, it, they.
Noah works here, doesn't he?
Noah works here, doesn't he?
Works is Present Simple, and the subject Noah corresponds to he, so doesn't he is required.
The buses arrived early, didn't they?
The buses arrived early, didn't they?
Arrived is Past Simple; the tag uses didn't, and the plural the buses is replaced with they.
The modal verb is repeated
With can, could, will, would, and should in this basic pattern, repeat the modal verb in its negative form. Other modal constructions may have special features, so do not apply this pattern automatically to every case.
Do not replace the modal verb with do or be. After You can join, the correct tag is can't you, and after She will call, it is won't she.
The contractions can't and won't are not formed by simply adding n’t to the spellings can or will, so their forms must be memorized.
can/could/will/would/should → negative form in the tag
You can stay, can't you?
You can stay, can't you?
Can is repeated in the negative form can't; the subject you does not change.
Lena will call, won't she?
Lena will call, won't she?
Will changes to the contracted form won't, and the name Lena is replaced with she.
The subject in the tag is a short pronoun
In a standard tag, replace a noun or name from the main clause with a pronoun: Marta → she, Mr Lee → he, the phone → it, the students → they.
The pronoun must preserve person and number. Use they for two people or for plural subjects; the form for you does not change.
After I am, the standard negative tag is aren't I. This is an established exception: I'm next, aren't I?
subject → corresponding pronoun; I am → aren’t I?
- subject / S —
- The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
- pronoun —
- A word used instead of naming a person or thing: I, you, she, it, they.
These keys are yours, aren't they?
These keys are yours, aren't they?
The plural these keys is replaced with they; are is repeated as aren't.
I'm on the list, aren't I?
I'm on the list, aren't I?
After an affirmative I am, standard English uses the special form aren't I.
Limits of the rule and carrying it into conversation
This rule practices only an affirmative main clause with a negative tag. A negative sentence with an affirmative tag, a tag after a command, and let's + shall we belong to neighboring patterns.
Intonation can show the degree of confidence: a falling tone often sounds like expected confirmation, while a rising tone sounds like a less confident check. The text-based self-check here evaluates meaning and grammatical form, not pronunciation or speech melody.
Before producing your own sentence, take four steps: formulate a positive idea, identify its auxiliary or tense, form the negative, and replace the subject with a pronoun. Natural wording may differ from the example if these decisions and the communicative intention are preserved.
idea → affirmative statement → required negative auxiliary → pronoun?
- auxiliary —
- A helping verb used to form tenses, questions or negatives: do, have, be.
- pronoun —
- A word used instead of naming a person or thing: I, you, she, it, they.
The meeting starts at nine, doesn't it?
The meeting starts at nine, doesn't it?
The speaker expects the time to be correct and asks for confirmation using the target form.
The meeting doesn't start at nine, does it?
The meeting doesn't start at nine, does it?
This is the grammatical pattern “negative statement + affirmative tag,” but it falls outside the scope of the current rule.
Common mistakes
Incorrect:She likes coffee, isn't she?
Correct:She likes coffee, doesn't she?
In the Present Simple with an ordinary verb, likes requires does; there is no be in the main clause.
Incorrect:They arrived early, don't they?
Correct:They arrived early, didn't they?
Arrived is in the Past Simple, so the tag must also use the past tense: didn't.
Incorrect:Mark can swim, doesn't he?
Correct:Mark can swim, can't he?
The modal can is repeated in the tag; the auxiliary do is not needed here.
Incorrect:The keys are here, isn't it?
Correct:The keys are here, aren't they?
The plural the keys requires the pronoun they and the corresponding form of are.
Incorrect:You have finished, don't you?
Correct:You have finished, haven't you?
Have is the auxiliary in the Present Perfect, so it is repeated in the tag.
Incorrect:I'm next, isn't I?
Correct:I'm next, aren't I?
The standard negative tag after I am has the established form aren't I.
