The Modal Helping Verb is another faithful sidekick to The Verb, and this helpful Verb Team member has the power to modify the Main Verb in order to help a sentence express possibility, necessity, or expectation.
Here’s an example:
I may spare your planet.
The main verb of this sentence, “spare,” is being assisted by a modal helping verb, “may,” to help it express possibility.
Without the aid of the modal helping verb, “may,” the main verb of this sentence would only be able to express a basic state of action, “I spare.”
But with the modal helping verb’s assistance, the main verb, “spare,” can make the shift into expressing the possibility of the action, “I may spare.”
The chart below is a list of modal helping verbs and how they’re used to help the main verb of a sentence.
