4. ‘Every’ becomes ‘there in no ...but’
Example:
Affirmative: Every mother loves her child.

In case of ‘everybody’, an affirmative sentence can also be changed into negative using
‘nobody’ and ‘opposite of verb/adjective’:

Affirmative: Everybody likes flowers.
Negative: Nobody dislikes flowers.
5. ‘Always’ in affirmative becomes ‘never + opposite word’ in negative statements:
Example:
Affirmative: I am always against of smoking.
Negative: I am never in favour of smoking.
6. Universal truths are changed into ‘interrogative negative sentences’:
Example:
Affirmative: Knowledge is power
Negative: Isn’t knowledge power?
7. Many affirmative can be changed into negative by using negative word ‘Not’ and an
‘opposite word’ of the verb:
Example:
Affirmative: I missed the train.
Negative: I could not catch the train.

8. ‘Sometimes’ in affirmative becomes ‘not always’ in negative:
Example:
