Learning how to change a sentence into negative form is an important part of English grammar. A negative sentence shows that something is not true, does not happen, or is denied.
In this guide, you’ll learn simple rules, clear examples, and practice sentences to easily convert affirmative sentences into negative ones.
What is a Negative Sentence?
A negative sentence is a sentence that expresses no, not, or never.
Examples:

👉 Words like not, never, no make a sentence negative.
How to Change a Sentence into Negative
Follow these simple steps:
1. Find the verb
Identify the main verb or helping verb in the sentence.
2. Add “not”
- If there is a helping verb → add not after it
- If not → use do / does / did + not
3. Adjust the verb form
Use the base form of the verb when using do/does/did
Rules with Examples
1. With “Be” verbs (is, am, are, was, were)
Just add not
- She is happy → She is not happy
- They are ready → They are not ready
2. With simple present tense
Use do/does + not
- I like apples → I do not like apples
- He plays cricket → He does not play cricket
3. With past tense
Use did + not
- She went home → She did not go home
- I saw him → I did not see him
4. With modal verbs (can, will, must)
Add not
- I can swim → I cannot swim
- She will come → She will not come
