usually indicates the "largest" time or place, and at usually

indicates the "smallest" time or place.

At, In and On: Prepositions of Place

We use at to talk about a place we think of as a point rather than an area, and about

an event where there is a group of people:

I arrived at Putna Station at 7:30. We last met at the conference in Italy. We were waiting at the far end of the room. There were very few people at Danas party.

We use on to talk about a position touching a flat surface, or on something we think of

as a line such as a road or river:

Is that a spider on the ceiling? (Notice we also say on the wall/floor) She owns a house on the Swan River.

We use in to talk about a position within a larger area, or something within a larger

space:

Theres been another big forest fire in Germany She looked again in her bag and, to her relief, there were her keys.

We usually use at before an address and in or on before the name of a road:

Theyve opened an office at 28 Lees Road The church is in/on Park Road

However, we sometimes use on instead of in when we talk about long streets or

roads:

The town is on the Pacific Highway.We can use at instead of in when we use a street name to refer to an institution in

that street:

There was an important meeting of ministers at Downing Street today.But notice that we say on Wall Street to mean the financial institution.
