'Going to'

present-future structure to talk about the future


 

BE GOING TO :
The structure be going to is mainly used to talk about plans and intentions, or to make predictions based on present evidence. It is most commonly used in conversational English.

In very informal spoken English, going to is sometimes shortened to gonna.

Be going to is used to talk about plans and intentions, usually when the decision has already been made.
