Modal verbs
Before we can really get to the bottom of ‘What is a modal verb?’ we need to start with
modality. While this might seem like an odd place to begin our guide, it’s important to know about
modality in order to understand modal verbs and the roles that they perform. So, to start us off,
what’s modality?
A modal verb, also known as a modal auxiliary verb, is a type of word that is used to modify
the modality of a main verb. Modal verbs are a kind of auxiliary verb, they are important because
they can affect the meaning of a sentence. Auxiliary verbs can help form the mood, tense and voice
of
other verbs, commonly using ‘be’, ‘have’ and ‘do’. Whereas
modal auxiliary verbs more
specifically affect the ‘mode’ of a sentence.
