Modals, also known as modal verbs or modal auxiliaries, are a category of auxiliary verbs that express various shades of meaning, including possibility, necessity, ability, permission, obligation, and intention. They are used to modify the main verb in a sentence and provide additional information about the action or state.
Common modal verbs in English include "can," "could," "may," "might," "must," "shall," "should," "will," "would," "ought to," and "need to." These modals are followed by the base form of the main verb.
Modals are versatile and have different functions depending on the context in which they are used. For example:
Modals can also be used to express politeness, make requests, give orders, express certainty or uncertainty, speculate about the past, and more.
One notable feature of modals is that they do not take the -s or -es ending in the third-person singular form. They remain the same regardless of the subject.
Understanding modals is important for effective communication, as they allow for nuanced expression of various attitudes, obligations, permissions, and possibilities. By using modals appropriately, we can convey our intentions, obligations, and opinions in a precise and nuanced manner, adding depth and clarity to our language.
