Overview
'Be going to' is used for intentions and plans already decided before speaking (I'm going to study medicine), and for predictions based on present evidence (Look at those clouds — it's going to rain). It is formed with am/is/are + going to + base verb and is distinct from 'will', which is used for unplanned decisions.
