Question

Whats is the degree of certainty?

Answer 1

When using the modal verb will to discuss certainty you are talking about the future (not the present or past). There are different modal verbs you can use to express different degrees of certainty, but you can also use adverbs to express degrees of certainty. Using different adverbs to express certainty may be easier for you to learn than learning different modal verbs that express certainty. One of the easiest modal verbs to learn is the modal verb ‘will’ that is used to discuss the future. Using the modal verb ‘will’ and ‘won’t’ is one of the most common ways of expressing the future, for example:

I will go to school tomorrow.

or

I won’t go to school tomorrow.

There are number of adverbs you can add to simple sentences like these examples that add meaning related to certainty and that don’t require you to become familiar with the use of other modal verbs like: could, would, and should.

Some of the most common adverbs related to certainty include: certainly, definitely, probably, and possibly.

Here is how these adverbs rank on a continuum in terms of certainty. Keep in mind that if you are ‘unsure’ this means you don’t know, if you are ‘sure’ this means you know something without a doubt.

not sure ———-> sure

possibly —- probably —- certainly —- definitely

Now, you can add these adverbs to sentences about the future (using the modal verb will) to give more meaning about the certainty of future actions.

Here are some examples:

I will probably get home at 5:00pm.

Ezra will certainly be visiting us next week.

Eliza will possibly go out for lunch with her coworkers.

We will definitely be laid off if the company’s income doesn’t improve.

As you can see in these examples the adverbs related to certainty is placed between the modal verb ‘will’ and the action verb of the sentence. I hope you have found this explanation of how to use adverbs with the modal verb will to express degrees of certainty helpful. You will definitely get better at expressing degrees of certainty with practice!
