Be going to
As a very commonly used multi-word verb form, in this case, a semi-auxiliary (i.e. it always needs a main verb, in this example, "make") to express future intention - I'm going to make a nice cup of tea.; also with future intention where a prediction is made based on evidence visible to the speaker Look at those clouds, it's going to rain, Look at that lady, she's going to have a baby; a warning You're driving too fast, you're going to kill us all!
- to predict the future based on evidence in the present (Look at that cloud - we're going to get soaked!);
- to make predictions about future events that are outside our control (I've spoken to them about it, but they're going to do whatever they want.)
The general form is:
- "Subject is going to do something".
This follows the standard rules for making questions and negation.
Often pronounced "gonna".
This is less used in formal writing.
Confusion with diary future
Learners - and often teachers - are likely to confuse "going to" with uses of the diary future that use go. In going to, going must be followed by a verb; i.e. "going + to-infinitive". The diary future can use the form "going" followed by a prepositional phrase ("to + noun phrase"). Compare "I'm going to go to the movies tonight" (using going to) v. "I'm going to the movies tonight" (diary future).
