MODAL VERB
A modal verb is a kind of auxiliary verb that is used to express modalities (the states or ‘modes’ in which a thing exists) such as possibility, ability, prohibition and necessity. Some common examples of modal verbs include should, must, will, might and could.


What is modality?
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?
When we talk about modality in this context, what we mean is the particular state, form or ‘mode’ in which something exists or happens. In grammar, modality is used to demonstrate necessity and authority. A low modality word like ‘could’ is a lot less convincing than a high modality word such as ‘must’.

What is a modal verb?

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.
These types of verbs can’t work alone, they need to be used with another verb in the sentence to have an effect on it. This is what makes them special! By now, you are probably wondering, ‘what is a modal verb going to do?’ Well, here is an example of how a modal verb can change a sentence:
‘I have clean hands.’
‘I must have clean hands.’
By adding the modal auxiliary verb ‘must’ to the sentence, it changes from being a statement of fact that the speaker has clean hands to indicate that they need to have clean hands. Instead of having clean hands, the speaker is now obliged to have them clean. Showing obligation is one of four key ways modal verbs can affect the other verbs in the sentence.
These are the ways the words can affect sentences with modal verbs examples:

• 
  obligation (‘You should do your homework’),
  
• 
  possibility (‘I might have pizza for tea’),
  
• 
  ability (‘You can ride a bike now’) or
  
• 
  prohibition (‘You may go out now’).
