What Are Adverbs of Probability?

Adverbs of probability are words that tell us how likely something is to happen. They help us express certainty, possibility, or doubt. These adverbs can describe something that is very sure, like “definitely,” or something that is uncertain, like “maybe” or “possibly.”

They are often used when making guesses, predictions, or plans. Some common adverbs of probability include: probably, maybe, certainly, possibly, definitely, perhaps, and likely. They usually come before the main verb, or after the verb “to be.”

How & Why Do We Use Them?

We use adverbs of probability to show how sure or unsure we are about something. For example, if you say, “She will definitely win,” you are very sure. But if you say, “She might win,” you are not as sure. These adverbs help others understand how strongly we believe something.

They are helpful in both speaking and writing. Whether you are making plans, talking about the future, or giving an opinion, these adverbs give important information. Learning to use them will help you sound more natural and express yourself more clearly.

Adverbs of Possibility

Adverbs of probability and possibility are similar, but they are not exactly the same. Adverbs of probability describe how likely something is to happen. They show a level of certainty or confidence. For example, saying “She will probably come” means you think there is a good chance she will. On the other hand, adverbs of possibility focus more on whether something can happen at all, not how likely it is. These words express that something is one of the options, even if it’s not very likely. Words like maybe, possibly, and perhaps are common adverbs of possibility. While both types talk about what might happen, possibility is more open-ended and uncertain.
