About These Exercises
These modal verbs exercises cover every English modal — can, could, may, might, must, should, have to, ought to, will, would, shall, and need to — across all six core functions: ability, permission, obligation, possibility, deduction, and advice. Practice modal verbs online with multiple choice, worksheets, and PDF downloads, all with answers and clear explanations. Whether you want a focused workout on a single modal (must vs have to, can vs be able to, may vs might) or mixed modals exercises that test every modal in one combined set, you'll find the right level here.
Modal verbs are different from regular verbs: they have only one form, never take -s in the third person, and are always followed by a bare infinitive. The real challenge isn't the form — it's choosing the right modal. "Must" and "have to" both express obligation but feel different. "Could" can mean past ability, polite request, or present possibility. The exercises with modal verbs below train the choice, not just the form, with instant feedback and context-rich examples.
Start with A2-level basics — can, must, should, may — then move through B1 contrasts (must vs have to, mustn't vs don't have to, may vs might vs could), and finish with B2 advanced material including past modals (should have, could have, must have, might have) and modal auxiliaries in formal writing. Every set is also available as a printable PDF worksheet for offline practice, classroom use, or exam preparation (Cambridge, IELTS, TOEFL).
