No more mistakes with MODALS! 3 Easy Rules

Introduction

This tutorial will help you master modal verbs in English, making it easier to communicate effectively. Modal verbs such as can, could, may, might, should, must, and others are used frequently, but they often confuse learners. By following three simple rules, you can avoid common mistakes and use modals with confidence.

Step 1: Use Modal Verbs As They Are

• Do not change the form: Modal verbs do not take on different forms based on tense.
  • Example: "He can swim" is correct. Do not say "He cans swim."
• Remember: Modal verbs remain the same regardless of the subject or tense.

Step 2: Use the Base Form of the Verb

• No "to" with modals: Always use the base form of the verb after a modal verb.
  • Example: "He might join us" is correct. Avoid saying "He might to join us."
• Key takeaway: After any modal verb, stick to the base form (e.g., join, swim, go).

Step 3: Form Negative Sentences Correctly

• Use "not" after the modal: When negating modal verbs, simply add "not" after the modal verb.
  • Example: "You should not smoke" is correct. Do not say "You don't should smoke."
• Exception for "have to": When negating "have to," use "don't":
  • Example: "You don't have to do this."
• Special note on "cannot": The word "cannot" is written as one word when used.
  • Example: "I cannot arrive on time."

Practice Exercises

• Identify the mistakes: Try to find what's wrong with the following sentences:
  1. "You must to finish your homework."
     • Mistake: "to" is incorrectly added.
  2. "He should to go now."
     • Mistake: "to" is incorrectly added.
  3. "You cannot to speak loudly."
     • Mistake: "to" is incorrectly added.

Conclusion

By following these three rules—using modal verbs in their base form, avoiding the infinitive "to," and correctly forming negative sentences—you can enhance your English communication skills.
