Can and Can't: Ability and Permission

What You Will Learn

You'll learn how to use can and can't to:
- Talk about what you're able to do (ability)
- Say what you're not able to do
- Ask for permission politely
- Give or refuse permission

Explanation (with real-life context)

Can is one of the most useful words in English. It has two main jobs:

1. Talking about ability — what you're good at or able to do:
- "I can cook Italian food" (this is my skill)
- "She can speak three languages" (this is her ability)
- "Can you swim?" (asking about someone's ability)

2. Asking for permission — politely asking if something is allowed:
- "Can I use your phone?" (asking if it's okay)
- "Can we sit here?" (asking if the place is available)
- "Can I have a coffee?" (in a café)

Can't (cannot) does the opposite — it shows inability or refusal:
- "I can't drive" (I don't have this skill)
- "You can't park here" (it's not allowed)
- "I can't help you today" (I'm not able to)

Examples (natural sentences from daily life)

Ability:
- "Can you cook pasta?" — "Yes, I can cook pasta well."
- "He can't play guitar, but he can play piano."
- "Can she swim?" — "No, she can't swim."

Permission:
- Job interview: "Can I ask you a question?" (Is it okay?)
- At a friend's house: "Can I use your WiFi password?"
- In a shop: "Can I try this jacket on?"
- Via WhatsApp: "Can you send me the homework?"

Common Mistakes

❌ "I can to speak English" — Don't use "to" after can
✅ "I can speak English"

❌ "Can I to go to the bathroom?" — Wrong structure
✅ "Can I go to the bathroom?"

❌ "She can not come" (two words)
✅ "She can't come" (use can't, not can not)

Quick Tips

• Can stays the same for all subjects: I can, you can, he/she/it can, we can, they can
• When asking permission, can sounds friendly and natural
• Can't is stronger than "cannot" — use can't in conversation
• Listen for "Can you...?" in real situations — it's asking ability OR permission depending on context
