We use adverbials of probability to show how certain we are about something. The commonest adverbials of probability are:
- Adverbials of probability 1
maybe and perhaps usually come at the beginning of the clause:
Perhaps the weather will be fine.
Maybe it won't rain.
Other adverbs of possibility usually come in front of the main verb:
He is certainly coming to the party.
Will they definitely be there?
We will possibly come to England next year.
or after the present simple or past simple of be:
They are definitely at home.
She was obviously very surprised.
But these adverbs sometimes come at the beginning of a clause for emphasis:
Obviously she was very surprised.
Possibly we will come to England next year.
