Answer 1

I'm not sure what you're asking, but I'll give it a shot.

The word "of" is used primarily to show possession or participation in a group. Examples:

He's the father of my child.
Susan is the only one of the students who knows the answer.
Some of his books are quite fascinating.
Which of the items did you wish to order?

The word "at" is used primarily to describe location or time. Examples:
John is at the office.
The kids are playing at Michael's house.
They're going to the play at 9 o'clock.

The word "on" is used primarily to describe a position above or over something else.
There is a squirrel on the roof.
Do you need a ladder to stand on?
What are you doing standing on that table?
Your watch is on the desk.


There are other ways to use these words, too, however. If you have a more specific question, we'd be glad to help.
