R2 Do Not

Lesson Two

Do – Making the negative

I do not = I don’t
We do not = We don’t
You do not = You don’t
You do not = You don’t
He does not = He doesn’t
She does not = She doesn’t
They do not = They don’t
It does not = It doesn’t

do + not = don’t

does + not = doesn’t


The verb “do” is a helping verb. Use “do” to make the present tense and the past tense negative. The verb “do” is also a main verb.

(Click here for a video that explains the difference between a helping verb and a main verb. )

Examples in the present tense:

I don’t work on the weekend. (present tense negative)

He doesn’t like to go to the store. (present tense negative)

They don’t have any money. (present tense negative)

Examples in the past tense:

The past tense form of “do” is “did.” Did + not = didn’tI

  • He didn’t work last night.
  • She didn’t go shopping yesterday.
  • We didn’t see that movie yet. .

Be careful: “Do” is also used as a main verb, but only for particular activities, such as housework, cleaning, studying, research, business, and shopping.

Examples in the present tense:

  • I don’t do the dishes every night. (do = wash)
  • She doesn’t do her grocery shopping at Cub. (do = go/finish)
  • They do not do their homework at the library. (do = complete)
  • Their company doesn’t do business in Minnesota.

Examples in the past tense:

  • I didn’t do the dishes last night.
  • She didn’t do her grocery shopping at Cub.

Separating the contraction creates emphasis


  • I do not want to do the dishes!
  • He does not have his license!
  • Please, do not put that hot pan on the counter!

Never put do + not + ____ing

He doesn’t going to work.( incorrect )

He doesn’t go to work. ( correct )

Avoid bad American grammar!

She don’t go to work on Sunday.

It don’t matter to me.

He don’t know.
