A. A friend of mine/a friend of Tom's etc.
We say 'a friend of mine/yours/his/hers/ours/theirs' (not 'a friend of me/you/him' etc.)
* I'm going to a wedding on Saturday. A friend of mine is getting married. (not 'a friends of me')
* We went on holiday with some friends of ours. (not 'some friends of us')
* Michael had an argument with a neighbour of his.
* It was a good idea of yours to go swimming this afternoon.
In the same way we say 'a friend of Tom's', 'a friend of my sister's' etc.:
* It was a good idea of Tom's to go swimming.
* That woman over there is a friend of my sister's.
B. My own.../your own... etc.
We use my/your/his/her/its/our/their before own:
my own house your own car her own room
You cannot say 'an own...' ('an own house', 'an own car' etc.)
My own.../your own... (etc.) = something that is only mine/yours (etc.), not shared or borrowed:
* I don't want to share a room with anybody. I want my own room.
* Vera and George would like to have their own house. (not 'an own house')
* It's a pity that the flat hasn't got its own entrance.
* It's my own fault that I've got no money. I buy too many things I don't need.
* Why do you want to borrow my car? Why can't you use your own?(= your own car)
You can also use... own... to say that you do something yourself instead of somebody else doing it for you. For example:
* Brian usually cuts his own hair. (= he cuts it himself; he doesn't go to the hairdresser)
* I'd like to have a garden so that I could grow my own vegetables. (= grow them myself instead of buying them from shops)
C. On my own by myself
On my own and by myself both mean 'alone'. We say:
on my/your own
on his her/own
on its our/their own
by myself/yourself (singular)
by himself/herself/itself
by ourselves/yourselves (plural)/themselves
* I like living on my own/by myself.
* Did you go on holiday on your own/by yourself?
* Jack was sitting on his own/by himself in a corner of the cafe.
* Learner drivers are not allowed to drive on their own/by themselves.
