Basic Negative Formation

To make a sentence negative in English, we typically add "not" after the auxiliary verb. If there's no auxiliary verb, we add "do/does/did" + "not".

Transformation Examples
POSITIVE
I like pizza.
NEGATIVE
I do not don't like pizza.
POSITIVE
She works in an office.
NEGATIVE
She does not doesn't work in an office.
POSITIVE
They went to the party.
NEGATIVE
They did not didn't go to the party.
Formation Rules
With Auxiliary Verbs

Subject + Auxiliary + NOT + Main Verb

  • I am not going.
  • She has not finished.
  • They will not come.
  • We can not see it.
Without Auxiliary Verbs

Subject + DO/DOES/DID + NOT + Base Verb

  • I do not like it.
  • He does not work here.
  • They did not call.
  • We do not understand.

Negative Contractions

In spoken English, we almost always use contractions. These are shortened forms created by combining the auxiliary verb with "not".

Common Negative Contractions
is not
isn't
are not
aren't
was not
wasn't
were not
weren't
have not
haven't
has not
hasn't
had not
hadn't
will not
won't
would not
wouldn't
cannot
can't
could not
couldn't
should not
shouldn't
Note: "Will not" becomes "won't" (not "willn't"). "Cannot" is written as one word and becomes "can't".

Negatives in Different Tenses

Avoiding Double Negatives

In English, we should avoid using two negative words in the same sentence. This is called a "double negative" and is considered incorrect in standard English.

INCORRECT: Double Negatives
I don't have no money.
(Two negatives: don't + no)
She didn't see nothing.
(Two negatives: didn't + nothing)
CORRECT: Single Negative
I don't have any money.
OR: I have no money.
She didn't see anything.
OR: She saw nothing.
Negative Words vs. Positive Words
Negative Words (Use with positive verb)
  • no - I have no time.
  • nothing - I see nothing.
  • nobody - Nobody came.
  • nowhere - I'm going nowhere.
  • never - I never smoke.
Positive Words (Use with negative verb)
  • any - I don't have any time.
  • anything - I don't see anything.
  • anybody - I don't know anybody.

Learning Tip: Practice negative sentences by taking positive sentences from books or conversations and making them negative. Pay special attention to verb forms and contractions. Record yourself saying negative sentences and listen back.
Common Challenge: Many learners struggle with "doesn't" for he/she/it in present simple. Remember: For third person singular (he, she, it), always use "doesn't" + base verb (without -s). Example: She doesn't like (NOT doesn't likes).
Critical Rule: Avoid double negatives in standard English. Use either a negative verb with "any" words OR a positive verb with "no" words. Example: "I don't have any money" OR "I have no money" (NOT "I don't have no money").
