NOTE 3. The expression TO BE GOING TO + Infinitive denotes:

(a) an intention or a decision;

E.g. They are going to get married.

(b) a prediction based on present evidence;

E.g. The sky is overcast. It ’s going to rain.

(c) a command or a refusal.

E.g. Ann, you ’re going to take those pills whether you like it or not!

I ’m not going to help you all the time.

In spoken informal English we often pronounce TO BE GOING TO + Infinitive as /gənə/. This can be shown in writing (especially in AmE) as GONNA. Mind that we use the Bare Infinitive after GONNA.

E.g. It ’s gonna be easy.

You ’re not gonna talk to me like that!
