When I asked something to my father like: “Dad can I borrow your car?” A typical answer was: “Yes you can but you may not.”
That is to say, that you use “can” for possibility and “may” for permission.
My friend may win the race.
The sky is very dark. It may rain.
It was raining and I got wet because I hadn't taken my umbrella with me.
I got soaked every day
Dana Lowry stepping in a puddle getting us all wet!
Don’t step in that puddle!
Watch (out for) the puddle!
I’m arriving earlier than I thought.
Could you give me back my book?
- Ana, could you give the book back to your brother?
I'll give it back to you now.
Thank you Thomas!
