How To Change Affirmative Sentence Into A Negative Sentence

How To Change Affirmative Sentence Into A Negative Sentence

There are two ways of turning an affirmative sentence into a negative sentence-

  1. Changing the meaning of a sentence.
  2. Without changing the meaning of a sentence.

1. Changing The Meaning of a Sentence

  • When we change the entire meaning of an affirmative sentence, it becomes a negative one.
  • Similarly, we can also turn a negative sentence into an affirmative one by changing its meaning.
  • Usually the three words – ‘no’, ‘not’ or ‘nothing’ are to place in affirmative sentences to make them negative. 

There are some examples of this process –
