Simple Future Tense

Definition…

 The future tense is a verb form that marks the event described by the verb as not having happened yet, but expected to happen in the future or to happen subsequent to some other event, whether that is past, present, or future.

The simple future is used…

to talk about things that will happen at a time later than now.

Simple Future has two different forms in English…

 "will" and "be going to." Although the two forms can sometimes be used interchangeably, they often express two very different meanings. These different meanings might seem too abstract at first, but with time and practice, the differences will become clear. Both "will" and "be going to" refer to a specific time in the future.

Be Going To Form

USE 1 "Will" to Express a Voluntary Action
"Will" often suggests that a speaker will do something voluntarily. A voluntary action is one the speaker offers to do for someone else. Often, we use "will" to respond to someone else's complaint or request for help. We also use "will" when we request that someone help us or volunteer to do something for us. Similarly, we use "will not" or "won't" when we refuse to voluntarily do something.
