Advice: 'should'

A2 Elementary

Use 'should' and 'shouldn't' to give advice or express that something is a good or bad idea. This modal verb helps you suggest actions without being as forceful as a command.

Overview

We use should to give advice or share an opinion about what is the right thing to do. It is a modal verb, which means it does not change its form based on the subject.

  • Use should for positive advice.
  • Use shouldn't (should not) for negative advice or to say something is a bad idea.

Form

Subject + should/shouldn't + base verb

The form is the same for all subjects (I, you, he, she, it, we, they). After 'should', always use the base form of the verb without 'to'.

Examples

Common mistakes

  • You should to see a dentist.

    You should see a dentist.

    Never use 'to' after the modal verb should.

  • She shoulds eat more vegetables.

    She should eat more vegetables.

    Do not add -s for third-person subjects; should is a modal verb.
