Modal Verbs
A modal verb is a helping verb such as can, could, may, might, must, shall, should, will or would that goes before a main verb to show how certain, possible or necessary something is. In Year 5 grammar, pupils learn to choose modal verbs carefully to show different levels of certainty, ability, permission or obligation. This helps writing become more precise and less like a plain statement of fact.
Before you start
Make sure you're comfortable with these topics first:
Method
- Learn the list of modal verbs: can, could, may, might, must, shall, should, will, would.
- Identify the main verb in the sentence that the modal verb is helping.
- Put the modal verb directly before the main verb in its base form, with no to, -s, -ed or -ing ending.
- Choose the modal verb that matches the level of certainty, ability, permission or obligation you want to show.
- Check the sentence still makes sense and use only one modal verb per verb phrase.
Worked example
Rewrite this sentence to show that the event is only possible, not certain: 'It will rain tomorrow.'
- Find the main verb: rain.
- Find the modal verb currently used: will, which shows certainty.
- Replace will with a modal verb that shows possibility, such as might or could.
- Rewrite the sentence with the new modal verb in place.
