How to Change a Sentence into Negative

Turning a positive (affirmative) sentence into a negative one is a basic yet essential part of learning English grammar. A negative sentence expresses the opposite of an affirmative statement and usually includes the word “not” or a negative helping verb.

Steps to Change a Positive Sentence into a Negative Sentence:

Locate the Main Verb
First, identify the main verb in the sentence. This helps determine where to place the negative word.
Insert “Not” After the Helping Verb
If the sentence includes a helping verb (like is, are, was, were, will, have, has), place “not” directly after it.
Example:
- Affirmative: She is happy.
- Negative: She is not happy.
Use “Do,” “Does,” or “Did” for Simple Tenses
For sentences without helping verbs, use do, does, or did plus “not” before the base form of the main verb.
Examples:
- Affirmative: They play football.
- Negative: They do not play football.
- Affirmative: He likes ice cream.
- Negative: He does not like ice cream.
- Affirmative: I saw the movie.
- Negative: I did not see the movie.

By understanding the verb tense and using the correct form of negation, you can easily transform positive sentences into their negative counterparts.
