3 Adverbs of Probability – Definitely, Probably, and Maybe

I want to teach you some helpful English that I taught to one of my private students here in Japan. We were talking and 3 common Adverbs of Probability came up. Definitely, Probably, and Maybe. The content of this post is from a real lesson, a natural conversation with some useful English grammar and expressions.


Definitely shows that we have high confidence. It is almost certain.
Probably shows some confidence but not certainty.
Maybe indicates something is possible to happen but not likely or unlikely. There is a 50/50 chance.

Keep reading for more real, natural English examples, from a native-speaking teacher. This is the best way to learn new English.

“If you buy a cheap computer, you will definitely have problems after a year or two. Cheap electronics never last.”

– Cheap electronics always break after a short period of time. It’s almost guaranteed.
“If you pay a high price, the thing you buy will probably be high quality.”

– There is a good chance that expensive goods will be of higher quality.
A: “Will you join us for a drink on Friday?”
B: “Maybe. I’m not sure if my boss wants us to work overtime or not.

– It’s possible that I can come but I’m not sure. The chances are about 50/50.

Real Lesson Example

My student and I were talking about clothes that are very cheap. I said it feels good to get a sweater for just a few dollars, but the problem is you get what you pay for.

I explained:

“If you pay a high price, the thing you buy will probably be high quality. If you pay a low price, the thing that you buy will be of lower quality. It won’t last very long or it will damage easily.”

My student understood the feeling, but he wasn’t sure about the word probably.

“the thing you bought will probably be high quality”

Probably – Meaning and Pronunciation

Probably is an adverb used to show how likely something is to happen or be true.

probably adverb – OxfordLearnersDictionaries.com 

We use the adverb probably quite often in English conversation. 

  • Mackenzie will probably be at the party. 
  • Leonard will probably be late for the meeting this afternoon, he’s always late. 

Let me give you a quick pronunciation note about the word probably.

The word probably has 3 syllables: PRAW-BAB-LEE. Native speakers,talking at natural speed will often reduce the word to 2 syllables – (I do this all the time!)

“I’ll probably [PRAW-BLEE] be late for dinner tonight, I have a meeting after work.”

An easy way to understand probability is with a simple chart. This is what I showed my student for these 3 common adverbs of probability.

definitely 100% I’m very confident that this is true
probably 70-80% I’m confident that this is true
maybe 50% This could be true or not true

If we say definitely
We are very confident that something will happen or that something is true. Our confidence is 100%.

“If you buy a cheap computer, you will definitely have problems after a year or two. Cheap electronics never last.” 

A: “Do you think Toyota makes quality cars?”
B: “Definitely. That company has a long history of making cars that perform well and last a long time.”

If we say maybe
We feel something may happen or may be true. Our confidence is around the middle. 50%

A: “Will you join us for a drink on Friday?”
B: “Maybe. I’m not sure if my boss wants us to work overtime or not. I’ll call you tomorrow at 5:00 and let you know.”

What Is The Difference Between PROBABLY And MAYBE?

What is the difference between probably and maybe?
Adverbs of Probability

Probably is somewhere between Definitely and Maybe. Our confidence level is more than 50%, but not quite 100%.

“If you pay a high price, the thing you buy will probably be high quality.”

Probably shows a higher level of confidence than maybe.
