In this article you’re going to learn some expressions to use with future tense and will (or won’t).
Will for Predictions
You can use I will (or you will, he will, she will, etc.) for predictions.
If you think you will stay home tonight, you can say: I will stay home tonight.
Or: I think I will stay home tonight.
Or if you don’t stay home, then you can say: I won’t stay home tonight.
Okay, so far that’s simple, right?
Now you can also add words that indicate that you are less certain, or more certain.
For instance, you’re fairly certain you will want to stay home tonight.
So you say: I will certainly stay home tonight.
If I’m a hundred percent sure, I will say: I will definitely stay home tonight.
If you’re not so sure, you can say: I will probably stay home tonight.
Now with Won’t.
You can express that you’re more or less certain that you won’t stay home tonight.
Sorry that I’m using the same boring sentence all the time, but that is to make it clearer for you.
You’re sure that you won’t stay home tonight. So you say: I will certainly not stay home tonight.
Or if you want to use the contraction (won’t), say: I certainly won’t stay home tonight.
Tip: Please note something important here, which is that certainly will comes after will if you don’t use the contraction, and before won’t if you use the contracted form.
You’re absolutely sure that you won’t stay home tonight, so you say: I will definitely not stay home tonight. Or: I definitely won’t stay home tonight.
You’re not absolutely sure that you’ll stay home, so you say: I probably won’t stay home tonight.
Most Certainly and Almost Certainly Etc.
You can also add: Most certainly, almost certainly, almost certainly not, most probably, most definitely. These add-ons of most and almost don’t add that much meaning. Almost certainly means more or less the same as most certainly. Perhaps most certainly is a little stronger (a little more sure) than almost certainly. The more precise you want to be in the way you talk (and write), the more of these little subtle words you can use. You don’t have to use them. It’s up to you. But people will use these expressions a lot and that’s why you need to know them.
