Adverbs Of Certainty

Adverbs of certainty express how certain or sure we feel about an action or event.

Common examples are: certainly, definitely, probably, undoubtedly, clearly, obviously etc.


Adverbs of certainty usually go in mid position. They are placed after auxiliary verbs and before other verbs. When there are two or more auxiliaries, the adverb goes after the first.


Perhaps and maybe are exceptions to this rule. They usually go at the beginning of a clause.
