Negation: Definition, Rules & Examples

Negation, as maintained by the likes of Merriam Webster refers to

“the action or logical operation of negating or making negative”.

In simpler terms, negation defines the polar opposition of affirmative, denies the existence or vaguely – a refutation. This is also known as “Not”. Classical logic resembles negation with truth function which takes truth to falsity and is perfectly capable of running the opposite operation. It denies the truth of a sentence. It’s just the conversion of the affirmative sentence which converts the simple affirmative sentence into negative.


  • I like to sing = I do not like to sing.

Double Negative

Double negative on the other hand, simply defines the existence of two forms of negation in the same sentence. Please, notice that a double negative can often result in an affirmation in the English language (e.g., He hardly stops for small-talks). The rhetorical term for such a phenomenon is ‘litotes’.


  • I can not find him nowhere.

Uses of Double Negative

Double Negative can be used in two ways. They are:

1. Using negative words

such as never, nobody, anyone, nothing, nowhere, etc


  • He cannot go nowhere without informing me

2. Using prefix

Such as ir, un, non, pre, anti, il, im, etc.


  • John is not uncontrollable by his family member though he is a special child.

More examples of negation of using prefix

In modern English, Double Negatives are highly avoidable as it is grammatically wrong. We know we cannot use more than one negative word in a statement. It usually used in informal conversation or speech and in songs’ lyrics as well. To form a correct sentence, we must avoid using a double negative in a single sentence formally.
