Grammar explanation

We can show how certain we are about the future by using modal verbs and other expressions.

Modal verbs and adverbs

We can use modal verbs (such as will, might, may or could) and adverbs (such as probably and definitely) to show how sure we are.

Very sure

People will definitely work from home more in the future.
Robots definitely won't replace all human jobs.


Donna will really enjoy this film.
You won't regret it.

Almost sure

He probably won't have enough time.

Not sure

I might go to the party, but I'm not sure yet.
He hasn't studied much, so he might not pass the exam.

When you are not sure, we can also use may, could and may not. However, we don't usually use could not to talk about the future.

Other expressions

We can also use other expressions such as be bound to and be likely to, or verbs such as think and doubt.

Very sure

He's bound to feel nervous before his driving test.
She's certain to get that job!
He's certain that he'll get here on time.

Hello, would you please explaine the usage ofuch + chance (singular) as in your example: /There's not much chance that I'll finish this essay tonight./ Thanks in advance

Hello Staciii

This means the same thing as 'little chance'. The Longman Dictionary entry for 'chance' lists 'no chance', 'little chance' and 'not much chance' together (see the Adjectives section of the list of collocations).

All the best
