Modal Verbs
Can, Could, May, Must, ShouldExpress ability, permission, obligation, and possibility with modals!
📖 Let’s Learn Modal Verbs!
Modal verbs are special helping verbs that express ability (can), permission (may), obligation (must), possibility (might), and advice (should). They add shades of meaning to your sentences!
Modals don’t change form — no -s, no -ed, no -ing! “He can swim” (not “He cans swim”). They always come before the base form of the main verb.
💡 The Rule
Modals express different meanings:
can/could = ability, may/might = possibility/permission,
must = obligation/necessity, should = advice,
would = polite request/imaginary
🎯 Key Concept
🎛️ Can = I am able to (ability)
🎛️ May = I am allowed to / It is possible (permission/possibility)
🎛️ Must = I have to / It is necessary (obligation)
🎛️ Should = It is a good idea (advice)

0/8Fun Facts
English has about 9 modal verbs: can, could, may, might, must, shall, should, will, would. They are called “defective verbs” because they don’t have all the usual verb forms (-s, -ed, -ing)!
In Indian English, “May I…” is used much more than in American English for asking permission. Indian schools traditionally teach “May I come in?” — which is perfectly correct and very polite!
🧠 Tips for Parents
Modal in Daily Life
Use modals naturally: “You SHOULD brush your teeth.” “You MUST wear your helmet.” “CAN you clean your room?” Daily exposure!
Permission Practice
Have your child ask for things using different modals: “Can I…?” → “May I…?” → “Could I…?” Builds politeness awareness.
Strength Comparison
“What’s the difference between SHOULD and MUST?” SHOULD = advice, MUST = no choice. Understanding the strength scale is key!
