The Difference Between Don’t and Doesn’t

Both don’t and doesn’t are short forms (contractions).

• Don’t = do not

• Doesn’t = does not

They are used to make negative sentences in the Present Simple tense.

Subject-Verb Agreement

The choice depends on the subject of the sentence:

I, you, we, they - use don’t

• I don’t like pizza.

• You don’t understand.

• We don’t watch TV in the morning.

• They don’t play football.

He, she, it - use doesn’t

• He doesn’t eat meat.

• She doesn’t go to school on Sundays.

• It doesn’t work anymore.

Quick Reminder

• With doesn’t, the main verb stays in the base form (no s at the end).
  
  He doesn’t likes music. - WRONG
  He doesn’t like music. - CORRECT

• Don’t and doesn’t are only for the Present Simple. For the past, we use didn’t.
