Negation

Saying no with not, and when do-support is needed.

S + Aux/Modal + not + V | S + don't/doesn't/didn't + V1

The particle not is added right after the auxiliary or modal verb. In Present Simple and Past Simple without another auxiliary, do-support is used: do/does/did + not + V1.

Examples

  • I don't like this rate.
  • She hasn't sent the POD yet.
  • We can't confirm the slot today.

  • I not like it.

    I don't like it.

    Present Simple without a modal or other auxiliary needs do-support: don't like.

Common mistakes

  • not placed right after the subject with no auxiliary: I not like it → I don't like it.
  • Double negatives: I don't have no invoice → I don't have an invoice / I have no invoice.
