This comprehensive guide will equip you with all the necessary knowledge to master Modals.

By the end of this blog post, you'll feel confident in tackling any Modal-related question on your CBSE Class 10 English exams. Let's get started!
Modals are special helping verbs that add extra meaning to the main verb in a sentence. They don't stand alone but work with other verbs to express things like:
- Possibility: Might, may, could
- Ability: Can, could
- Permission: Can, may, could
- Obligation: Must, should, have to
- Advice: Should, ought to
- Willingness: Will, would
So, instead of just saying "I go," you can use modals to express your feelings and intentions more precisely.
For example:
- "I can swim." (Ability)
- "You should study for the test." (Advice)
- "May I borrow your pen?" (Permission)
Modals are essential for effective communication as they help you express yourself with greater nuance and clarity.
Table summarizing the most common modals and their primary functions:
| Modal | Primary Functions |
|---|---|
| Can | Ability, possibility, permission |
| Could | Ability (past), possibility, permission (polite) |
| May | Possibility, permission |
| Might | Possibility (less certain than may) |
| Shall | Obligation, suggestion (formal), future tense (formal) |
| Should | Obligation, advice, suggestion |
| Will | Willingness, prediction, future tense |
| Would | Willingness (past), preference, polite request |
