The simple future tense is a verb tense that’s used to talk about things that haven’t happened yet.
This year, Sheryl will read War and Peace. It will be difficult, but she’s determined to do it.
Use the simple future to talk about a condition or action that will begin & end in the future.
The formula for the simple future is will + [root form of verb].
I will learn a new language. Sheryl will read that book. My brothers will sleep till noon if no one wakes them up. You will see what I mean.
There is another way to show tell that something will happen in the future. It follows the formula [am/is/are] + going to + [verb in root form].
I am going to learn a new language. Sheryl is going to read that book. My brothers are going to sleep till noon if no one wakes them up. You are going to see what I mean.
The “going to” construction is common in speech & casual writing. Keep in mind though that it’s on the informal side, so it’s a good idea to stick to the will + [root form] construction in formal writing.
