Marvellous Modals

Understand and use the English modals like a pro

Really understand the English modal verbs


This modals course covers all the English modal verbs (can / could / will / would / shall / should / must / might / may) and how they are used in English.

Serious explanations


I explain everything you need to know clearly and in detail. You can watch my videos or read the explanations.

Practice that works


Exercises, PDFs, reviews. You'll know the tenses properly (and be able to use them) by the end of the course.

'My English is good, but I'm still not confident about the modal verbs'


The modals are tricky! This course explains all the theory about modal verbs and almost every use, including advanced uses.

There are videos, quizzes, exercises and flashcards to help you remember everything.

It includes the nine basic modal verbs, as well as phrasal modals and similar expressions like 'be supposed to', 'had better', 'be able to' and so on.
