Adverbs of Possibility
An adverb of possibility is a word such as perhaps, maybe, possibly, probably, certainly or definitely that tells the reader how likely something is to happen. In Year 5 English, pupils learn to place these adverbs before the main verb or at the start of a sentence to show different degrees of certainty. They often work alongside modal verbs to add nuance and precision to writing.
Method
- Learn common adverbs of possibility: perhaps, maybe, possibly, probably, certainly, definitely, surely.
- Decide how likely the event or idea is: use perhaps or maybe for low certainty and definitely or certainly for high certainty.
- Place the adverb at the start of the sentence followed by a comma, or directly before the main verb.
- Check the adverb matches the modal verb or tone of the rest of the sentence so the meaning stays consistent.
- Read the sentence back to make sure the level of certainty makes sense in context.
Worked example
Add an adverb of possibility to show you are almost completely sure the school trip will go ahead: 'The school trip will go ahead.'
- Decide the level of certainty needed: very high, but not stated as a plain fact.
- Choose an adverb that matches this level: definitely or certainly.
- Decide where to place it: directly before the verb will go.
- Write the new sentence with the adverb inserted.
