The phrases ‘will’ and ‘going to’ are very commonly used to express oneself in the future tense. It’s important however to know the difference in how they are used and under what circumstances should they be applied.
If you’re making a quick decision about something or someone, you’re going to use ‘will’ instead of the alternative of ‘going to.’ Also if you’re offering to help or assist someone, then you would use ‘will’ as well. When it comes to making a promise or a threat, ‘will’ is what you should be using before the verb. Lastly, ‘will’ is also used when you want to refuse a gesture or a gift from somebody. The five instances of making a quick decision, offering something, making a promise and/or threat, and refusing a gesture or a gift will all use ‘will’ when it comes to the future tense.
1.) I will buy you dinner tomorrow night.
2.) He will help you get out of the car.
3.) She will promise us to watch the dog while we go out to brunch.
4.) If they don’t stop marching, we will shut down the bridge to stop them.
5.) They won’t help us if we are not willing to cooperate with them.
When it comes to using ‘going to’, the circumstances of usage are not as frequent when compared to using ‘will’ for the future tense. When ‘going to’ is placed in a sentence, it’s often for discussing a prior plan that you have confirmed with friends, family, or other people in your life and is a definitive plan. When something is likely to happen and the result is inevitable based on the current evidence, you would also use ‘going to’ to describe the outcome. The last instance where you would use ‘going to’ over ‘will’ is when something imminent is about to happen and there’s not much time left until it occurs such as an event.
1.) I’m going out dancing with my best friends tonight at the Salsa club in Havana.
2.) New England is likely going to win this football game. They’re up by 21 points at halftime.
3.) The race is going to start immediately after the gun fires in the air.
The one instance where ‘will’ and ‘going to’ overlap with each other in terms of usage deals with making predictions that are likely to happen in the future. In this regard, both ‘going to’ and ‘will’ are equal and both create the same kind of meaning in the sentence.
1.) I think it’s going to rain tomorrow evening in Seattle.
2.) I think it will rain tomorrow evening in Seattle.
As you can see in this example above, there is no discernible difference between these two sentences in terms of meaning even though they use ‘going to’ or ‘will’ interchangeably without any issues. If a student of the English language is to master the future tense in grammar, he or she will need to know the differences and similarities between the phrases ‘will’ and ‘going to.’ They can be applied in a number of different ways so it’s important to study the examples above and also think about their reasons for being used in the future tense.
