Modal Verbs - English Grammar Exercises

Modal verbs—like Can, Must, and Should—are special tools that change the meaning of your sentences. They express ability ("I can speak"), obligation ("She must arrive"), and advice ("He should study"). Unlike other verbs, they are very simple because they never change for the subject!

In this module, you’ll learn the most common modal verbs and how to use them with the base form of other verbs. You’ll practice with 25 exercises that cover daily duties, possibilities, and polite requests.

Key Rule: Base Form

One of the most important things to remember is that modal verbs are always followed by the base form of the next verb. No "-s", no "-ed", and definitely no "to" (except for "have to").

Tricky Cases

Watch out for common mistakes when using Modal Verbs. Pay close attention to subject-verb agreement and how different contexts can change the correct form. Some patterns might seem similar but have important differences.

Remember that context matters. The same sentence structure might work differently depending on whether you're talking about the past, present, or future, or whether you're making a statement or asking a question.

What You'll Practice

The 25 exercises give you sentences where Modal Verbs needs to be used correctly. You'll practice:
