"Can" vs "May": Permission and Ability Difference
Can और may का अंतर ability, permission, possibility, formal usage, common mistakes, exam traps और practice questions के साथ समझें।
Classroom में एक पुराना correction बहुत सुनने को मिलता है:
Student: Can I leave the room?
Teacher: You can, but may you?
Joke पुराना है, पर grammar point काम का है। Can मुख्य रूप से ability या practical possibility बताता है। May permission या formal possibility बताता है। रोज़ की English में लोग permission के लिए “can” भी बोलते हैं, लेकिन formal writing और exams में difference समझना ज़रूरी है।
- Can = ability, capacity, skill, या practical possibility.
- May = permission, polite/formal permission, या uncertain possibility.
Rule box: Ability के लिए can। Formal permission के लिए may।
Compare करें:
He can speak three languages.
May I speak now?
पहला sentence ability बताता है। दूसरा permission मांगता है।
“Can” और “may” modal verbs हैं। Modal verbs का basic pattern यह है:
| Pattern | Example |
|---|---|
| subject + modal + base verb | She can solve the problem. |
| modal + subject + base verb | May I enter? |
| subject + modal + not + base verb | Students may not enter without permission. |
Modal verb के बाद main verb का base form आता है।
सही: He can speak English.
गलत:He can speaks English.
| Use | Better Modal | Example |
|---|---|---|
| Ability | can | I can swim. |
| Informal permission | can | Can I borrow your pen? |
| Formal permission | may | May I leave early? |
| Rule-based prohibition | may not | Visitors may not enter this area. |
| General possibility | can | Accidents can happen anywhere. |
| Uncertain possibility | may | It may rain tonight. |
“Can” और “may” चुनते समय यह method लगाएँ:
- Sentence ability या skill के बारे में है? Can use करें।
- Formal permission मांगनी या देनी है? May use करें।
- Casual spoken permission है? Can acceptable है।
- Rule, notice, या instruction है? May / may not बेहतर है।
- Possibility है? General possibility के लिए can, specific uncertain possibility के लिए may।

गलत: May you swim?
सही: Can you swim?
“May you…?” ability पूछने का normal structure नहीं है। यह blessing में आ सकता है, जैसे “May you succeed,” लेकिन वह अलग use है।
Conversation में “Can I leave?” normal है। लेकिन formal grammar questions में, अगर meaning permission है, तो may safer answer होता है।
Informal: Can I leave?
Formal: May I leave?
- May not = allowed नहीं है।
- Cannot / can’t = able नहीं है, possible नहीं है, या context के हिसाब से allowed नहीं है।
You may not park here. = Permission नहीं है।
I cannot lift this box. = Ability नहीं है।
General possibility के लिए can:
Too much sugar can harm your health.
Specific uncertain possibility के लिए may:
The train may be late today.
“Cannot” normally एक word में लिखा जाता है। “Can not” rare contrast में आता है, पर usual writing में cannot बेहतर है।
Correct: I cannot attend the meeting.
Common informal: I can’t attend the meeting.

| Students can not enter without permission. | Students may not enter without permission. | Formal prohibition. |
| Can I speak, Your Honour? | May I speak, Your Honour? | Formal permission. |
| She can goes now. | She can go now. | Modal + base verb. |
| It can rain tonight. | It may rain tonight. | Specific uncertain possibility. |
