Modal Verbs in English

Definition and Meaning  

A modal verb is an auxiliary verb that is used to express possibility, ability, permission, request, obligation, etc.


Two Types of Modal Verbs 

1. Principal Modals 

2. Semi-modals 


1. Principal Modals are the modal auxiliary verbs that have the following characteristics. 

1. They don't accept inflection–they don't end in s/es

2. They can't be used as infinitives like “*To can” or “*To shall”. They can't be used as participles like “*Canning” or “*Canned”. 

3. They use bare infinitives ( infinitives without “To”). Such as “Go” as in “I can go.” 


All Principal Modals:

Can, Could, Will, Would, Shall, Should, May, Might, And Must. 


2. Semi-modals are the modal verbs that express some modality like Obligation, Habit, etc., But they don't possess all the features or characteristics that the principal modal verbs do. 


Semi-modals are as follows:

Need, Dare, Ought to, Used to, Have to, Had better, etc.
