Examples of negative sentences say that something is not the case, usually by adding not or no to a positive line. The negative sentence swaps a fact for its opposite, so “She is ready” becomes “She is not ready.” Most of the work is done by a small auxiliary that carries the not.
Examples of negative sentences at a glance
- A negative sentence denies or rejects what a positive sentence states.
- With the verb be, not follows the verb directly.
- With a plain verb, do-support adds do not or does not.
- No modifies a noun, as in no time, rather than a verb.
- The commonest error is a double negative using two negative words.
What are negative sentences?
A negative sentence is a sentence that denies something, stating that a fact, action, or state does not hold. English builds the negative around an auxiliary, which takes the not, so the position of not depends on the verb in the sentence. The table shows how negation works for five common verb shapes.
| Element | How negation works | Example |
|---|---|---|
| be | add not after the verb | She is not ready. |
| modal | add not after the modal | They cannot stay. |
| present simple | do or does + not + base verb | He does not drive. |
| past simple | did + not + base verb | We did not see it. |
| perfect | not after have | I have not finished. |
Negation does not change a sentence’s tense or subject; it only reverses the truth of the statement. That is why the auxiliary, rather than the main verb, is where the negative is marked.
How do you form a negative sentence?
Forming a negative sentence means finding the auxiliary and putting not straight after it; when there is no auxiliary, do-support supplies one. The table lists the negative form for five tenses, so the pattern is visible at a glance.
| Tense | Negative form | Example |
|---|---|---|
| Present simple | do not / does not | She does not work here. |
| Past simple | did not | They did not call. |
| Present continuous | am / is / are not | I am not listening. |
| Past continuous | was / were not | We were not waiting. |
| Future | will not | He will not join us. |
The choice between does not and did not simply follows the tense of the positive sentence, so a negative never introduces a new time of its own.

Examples of negative sentences across contexts
Negative sentences appear wherever a speaker denies, refuses, or corrects, from a friendly chat to a formal report. Ten examples follow, each with the reason it works.
| Context | Negative sentence | Why this works |
|---|---|---|
| Everyday talk | I do not have my keys. | do-support with a plain verb |
| Workplace email | The report is not ready yet. | not after be, with yet |
| Classroom | Nobody has finished the test. | nobody already carries the negative |
| Shop | This is not the right size. | not after the verb be |
| Travel | The train does not stop here. | does not with a third-person subject |
| News report | The team did not comment. | did not for a past event |
| Doctor’s office | It does not hurt when I rest. | describes a symptom’s absence |
| Safety | Do not touch the wires. | a negative imperative |
| Academic writing | The results do not support the claim. | formal negation of evidence |
| Small talk | I have not seen that film. | a present perfect negative |
Negation with not or with no: which should you use?
Choosing between not and no depends on what follows the negative word. Not sits after an auxiliary and negates a verb, an adjective, or a whole clause, while no stands before a noun and negates that noun. The two are not interchangeable, and the table shows where each belongs.
| Feature | not | no |
|---|---|---|
| Position | after the auxiliary | before a noun |
| Example | She is not happy. | She has no time. |
| Register | neutral | slightly more formal or emphatic |
| With verbs | very common | never used directly before a verb |
| Best for | negating verbs and adjectives | negating a following noun |
Reach for not when the sentence denies an action or a quality, and for no when the sentence denies a noun. The two can even appear together, as in There is no milk, so I do not have any for the cake.
Word forms and grammar of negative sentences
The negative system is small: a handful of words do all the denying, and each has its own place. For a wide set of models, negative in a sentence examples show the same forms across registers, and a themed list such as negative words that start with a groups the everyday vocabulary of refusal.
| Form | Example | Note |
|---|---|---|
| not | I am not late. | the plain negative adverb |
| n’t | I’m not late. | the contracted form in speech |
| no | There is no milk. | no modifies a noun |
| none | None of them came. | a pronoun meaning not any |
| never | She never calls. | already negative, so it takes no not |
A longer denial often adds a reason clause, and adjective clauses in complex sentences show how that extra clause attaches without breaking the negative.
Common mistakes with negative sentences
Five slips appear when learners build a negative, and each one breaks the rule about where not goes or how many negatives a sentence may hold. A single clause carries one negative only, and once that rule is clear the errors stop.
Mistake 1: the double negative. Incorrect: I do not have nothing to say. Correct: I do not have anything to say. Rule: do not and nothing both mark the negative, so use one.
Mistake 2: missing do-support. Incorrect: He not works here. Correct: He does not work here. Rule: a plain present verb needs do-support for the negative.
Mistake 3: the wrong order after be. Incorrect: She not is ready. Correct: She is not ready. Rule: not follows the verb be.
Mistake 4: no before a verb. Incorrect: I no like it. Correct: I do not like it. Rule: no modifies a noun, not a verb.
Mistake 5: the contracted form in formal writing. Incorrect in a report: The council didn’t approve it. Correct: The council did not approve it. Rule: formal writing prefers the full forms do not and did not.
Practice using examples of negative sentences
- Fill in the blank: She ___ not like coffee.
- Choose the correct negative: (He not works here. / He does not work here.)
- Correct the error: I do not have nothing to say.
- Build a sentence: turn “They arrived early” into a negative past sentence.
- Spot the register: which suits a formal report, (a) The data didn’t change, or (b) The data did not change?
- Fill in the blank: a negative imperative begins with ___ plus the base verb.
Answers
- does, because a third-person subject needs does not.
- He does not work here, because a plain verb takes does not.
- I do not have anything to say, because only one negative is allowed.
- They did not arrive early, because did not marks the past negative.
- (b), because a formal report prefers the full form.
- Do, as in Do not touch, because the imperative uses do for its negative.

The bottom line
Examples of negative sentences turn a statement into its opposite by adding not or no in the right place. Not follows the auxiliary and negates a verb or an adjective; no stands before a noun and negates that noun. Keep one negative per clause, use do-support for a plain verb, and the negative form becomes as easy as the positive.
Frequently asked questions about negative sentences
What makes a sentence negative?
A negative sentence contains a word such as not, no, never, or none that denies part of its meaning. The negative word attaches to an auxiliary, as in does not, or to a noun, as in no time. Without one of these markers, the sentence states something positive.
Where does not go in a sentence?
Not goes straight after the first auxiliary, whether that is be, have, a modal, or the dummy do. So the sentence reads She is not here or He does not drive. When there is no auxiliary, do-support adds one for the not to attach to.
What is the difference between not and no?
Not is an adverb that follows an auxiliary and negates a verb, an adjective, or a clause. No is a determiner that stands before a noun and negates it, as in no money. Saying I have not money is wrong because not cannot modify a noun directly.
Can a sentence have two negatives?
Standard English allows only one negative per clause, because two would cancel out or sound non-standard, as in I do not have nothing. Use a single negative with a word like anything, as in I do not have anything. A double negative is fine only when a positive meaning is intended.
