Future Simple vs. Going to Future Simple (will): Use "will" when you make a decision at the moment of speaking or when you predict something based on what you think or believe. Examples: - I will help you with that. - I think it will rain tomorrow. Going to: Use "going to" when you have already decided to do something before the moment of speaking or when something is about to happen. Examples: - I am going to visit my friend this weekend. - Look at those dark clouds. It is going to rain soon.
