Modal Verbs: Overview

Modal verbs are very common and useful in English. We use them to talk about ability, permission, obligation, requests, offers, suggestions and more.

Modal verbs can express multiple states and intentions. Some of them have different meanings depending on a situation. For example, we can use the verb ‘can’ to talk about ability, possibility, to ask for permission, to make a request or to offer help.

How to use modal verbs

1. All modal verbs, except for ‘ought‘ and ‘have‘ require no preposition (‘to’) with the following verb:

  • I can dance.
  • You should go.
  • You must be careful.
  • I have to read a lot to become a good student.
  • You ought to observe the rules.

2. Modal verbs in English don’t add an ‘s’ for he/she/it. They are always followed by the main verb in the base form:

SubjectModal verbBase form of the verbRest of the sentence
I (you, he, she, it, we, they)candancevery well.

3. All modal verbs don’t require any auxiliary verbs to form questions and negative forms.
Negative statements are formed by adding ‘not’ after the modal verb:

  • You should not (shouldn’t) eat so much meat – it’s bad for you.
  • Jack can not (can’t) play tennis, but he likes playing football.

4. Questions with modal verbs are usually formed by swapping the subject and modal verb:

  • They should visit Egypt.
  • Why should they visit Egypt?
  • You may come in.
  • May I come in?
  • Tiffany can meet her friends tonight.
  • Can Tiffany meet her friends tonight?
