surely
certainly
undoubtedly
clearly

We usually use these with the future tense and the present tense.

I will definitely good.
The movie will undoubtedly be sold out.

But it is also possible to use them with the past tense to guess or make assumptions about the past.

She probably went home.
He definitely stole the diamonds.

Now, let’s see where we put these adverbs. It can be different depending on the verb tense and sentence.

Here is where we put these adverbs in the present tense and past tense.

Subject + adverb + verb…
Subject + be verb + adverb + (not)…

She definitely works here.
He probably likes sports.
She probably doesn’t like me.
I definitely need to shower.
He definitely went home.
They probably left early.
They are definitely brothers.
It is probably bad.
The girl is probably not a good student.
It was probably canceled.

If we are making a negative sentence, we do not use contractions. Put “not” after the adverb.

~~The movie isn’t probably good.~~
The movie is probably not good.

Here is where we put these adverbs in the future tense with “will”.

Subject + will + adverb + (not) verb…
Subject + will + adverb + (not) be…

I will probably go.
I will probably not go.
It will definitelyrain tomorrow.
She will probably not come.
He will definitely not come.
It will definitely not be good.
He will probably not be hungry.
He will certainly be upset.

If we are making a negative sentence, do not use the contraction “won’t” before the adverb. Put “not” after the adverb.

~~It won’t definitely rain.~~
It will definitely not rain.

Many English speakers use the contraction “won’t” after the adverb.

It definitely won’t rain.
She probably won’t be at the party.

Types Of Adverbs Pdf

Adverbs are used freely by most native English speakers. So, do not be surprised if you hear English speakers using the adverbs before “will”.

He definitely will not come.
She probably will quit.
She probably won’t be angry.
They surely won’t be happy.

If we use the present continuous or “going to + verb” to talk about the future, then we put the adverb after the “be verb”. Just like the present or past tense.

She is probably going to come.
They are definitely not going to be happy.
It is definitely not going to rain tomorrow.

Some adverbs of certainty go at the beginning of a sentence.
