Ought to: 4 Key Points to Remember when using ‘Ought To

  1. When “ought to“ comes after different pronouns, such as I, you, he, we, or they, it retains its original form. In other words, it doesn’t change like the verb “be” with “He, she or it”.
  2. Ought to cannot be used with another modal verb. For example, you can’t say: food prices ought to must be cheaper
  3. The infinitive form, the basic form, of the main verb is always used after ought to.
  4. And similar to most modals, ought to can’t be changed into the past or the future. You can still make a past form of ought to with ought to have + V3. For example:
  • I ought to have visited my teacher when he was sick.
  • We ought to have finished our studies before we left home.
  • You ought to have told me before.
