In general, we use: at for a POINT in for an ENCLOSED SPACE on for a SURFACE Jane is waiting for you at the bus stop. The shop is at the end of the street. My plane stopped at Dubai and Hanoi and arrived in Bangkok two hours late. When will you arrive at the office? Do you work in an office? I have a meeting in New York. Do you live in Japan? Jupiter is in the Solar System. The author's name is on the cover of the book. There are no prices on this menu. You are standing on my foot. There was a "no smoking" sign on the wall. I live on the 7th floor at 21 Oxford Street in London. Notice the use of the prepositions of place at, in and on in these standard expressions: at in on at home in a car on a bus at work in a taxi on a train at school in a helicopter on a plane at university in a boat on a ship at college in a lift (elevator) on a bicycle, on a motorbike at the top in the newspaper on a horse, on an elephant at the bottom in the sky on the radio, on television at the side in a row on the left, on the right at reception in Oxford Street on the way

Thank you.

On, at, and in....an easy way to pick which one is right is to picture it. For example with objects, use a car. "He was in the car" means he was actually inside of the car. "He was on the car" means he was actually on top of the car, like standing on the roof. "He was at the car" this ones a little weird because it COULD mean he's inside of the car or it could mean he's standing near the car. Prepositions in any language are super hard, it just takes practice to decide what's right/wrong, you'll get it!
