Understanding Modal Verbs in English

Introduction

• Modal verbs in English often cause confusion: can, could, may, might, must, shall, should, will, would.
• This lesson aims to clarify their functions with examples, quizzes, and a free PDF study guide.

Modal Verbs Overview

• Form: Modal verbs have a single form.
  • No adding "-ing" (e.g., could vs. coulding).
  • No "-ed" (e.g., must vs. musted).
  • No "-s" in third person singular (e.g., should vs. shoulds).
• Modals are followed by a base verb, not an infinitive (e.g., "I might bake").
• Questions: Formed by inverting subject and modal verb order (e.g., "Can I help you?").
• Negatives: Form with "not" (e.g., could not, should not).
  • Cannot is a single word.
  • Contractions: can't, won't. "Mayn't" is rare.
