    Differences between 'on', 'in' and 'at'

    One of the most difficulties in english...i think that is prepositions
    Could anyone explain the difference of using for the following prepositions?


    the common cases...when to use it...and if there is any exception...that doesnt follow the grammar content.

    Re: Differences between 'on', 'in' and 'at'

    "in" for inside of, "on" for on top of, and "at" for a point in space or time.

    He's in the bank. (inside its four walls)
    He's on the bank. (on top of its roof)
    He's at the bank. (a point in space; he could be in, on, or under the bank)
    He'll meet you at 5:00. (a point in time).

    Exceptions: vehicles

    On the bus doesn't mean you're on top of the bus. Rather, you're aboard the bus. Same holds true for planes, and boats, but not for cars.

    On the car means, you're on top of the car.

    Here're the rules:

    If you have to step up, as in walk onto a vehicle, you're getting on, you're are on board, on the plane, on the train, on the boat.

    If you have to crouch down to get into the vehicle, then you are getting in the car, and in the cab.

    Hope that helps.
