Future: be going to

A1 18 / 50

In short

Use be going to + base verb to talk about plans you decided before now, and predictions you can already see coming. The form is am/is/are + going to + base form.

The rule

We use be going to in two main ways:

  1. Plans and intentions - things you already decided before the moment of speaking.

    • I’m going to study medicine. (I decided this earlier.)
    • We’re going to paint the kitchen this weekend.
  2. Predictions from present evidence - you can see or feel that something will happen.

    • Look at those clouds - it’s going to rain.
    • She’s going to have a baby. (You can see it now.)

The first part (am/is/are) changes with the subject. The verb after going to is always the base form (no -s, no -ed, no -ing).

To make a negative, add not to be. To make a question, put be before the subject.

Forms & patterns

Subjectbe+ going to + base form

With there, be agrees with the noun that comes after it: There is going to be a delay. There are going to be delays.

Short forms:

They are not going toThey aren’t going to / They’re not going to

Short answers use only be:

QuestionYesNo
Are you going to help?Yes, I am.No, I’m not.
Is he going to drive?Yes, he is.No, he isn’t.

In if- and when-clauses, use the present simple for future time - We are going to get wet if it rains. We are going to start when everyone is here. Keep be going to after if when the clause reports a plan already made: If you are going to sell the piano, tell me first. In a when question, direct or reported, be going to is normal: When are you going to decide? (More in Zero & first conditional.)

Common mistakes

  • I going to call him. -> I’m going to call him. - you must keep am/is/are.
  • She is going to calls you. -> She is going to call you. - use the base form, never -s.
  • He is going to wrote a letter. -> He is going to write a letter. - base form, not past.
  • Are you going help? -> Are you going to help? - don’t drop to.
  • It goes to rain. -> It is going to rain. - it’s be going to, not go to.

Tips

  • In fast speech going to often sounds like “gonna” - that’s fine to hear, but write the full going to.
  • If a plan is already decided, or you can see the evidence now, choose be going to. If you decide while speaking, use will (see lesson 19).
  • going to go and going to come are correct, but people often shorten them: I’m going to the cinema instead of I’m going to go to the cinema.
  • A time word like tomorrow, next week, or tonight often signals this future.
