Prepositions of place: in, on, at
In, on and at are the three core prepositions of place in English: use at for a specific point (at the bus stop), on for a surface or line (on the table, on the coast), and in for an enclosed space or larger area (in the box, in London). Choosing between them depends on how you picture the space, not the object's real size.

Every answer at a glance
on
Buses, trains, planes, ships and bikes take on, even though you sit inside most of them.
I fell asleep on the train and missed my stop.
in
Small private vehicles that you sit inside, such as a car or a taxi, take in.
There's no room for another suitcase in my car.
at
When a building is just the place where something happens or where you meet, treat it as a point: at the airport, at school.
I'll meet you at the airport, by the arrivals board.
in
To stress being inside the walls rather than outside, use in: in the library, in the station.
It was pouring, so we waited in the station until the storm passed.
at
A place seen as a single point takes at: an address, a meeting point, an event, the top of a page.
The interview is at 22 King Street, on the third floor.
on
A surface or a line takes on: a wall, a table, a road, a river, a coast, and the floors of a building.
The hotel is on the coast, and our room was on the fifth floor.
in
An enclosed space or an area with borders takes in: a room, a box, a city, a country, a region.
The spare keys are in the kitchen drawer.
How to use prepositions of place: in, on, at
When do you use 'at' for place?
Use at when you think of a location as a single point: an address, a specific spot, or an event where people gather, rather than an area you can be inside or a surface you're on.
This is why at works for precise addresses, meeting points and events: the exact size of the place doesn't matter, only whether you're treating it as a point on a map.
- Let's meet at the reception desk at nine.
- The ambassador's residence is at 14 Park Lane.precise address → at
- We ran into an old classmate at the concert last night.an event as a meeting point
When do you use 'on' for place?
Use on for a surface, a line, or something that touches a flat plane: on the table, on the wall, on the ceiling. It also covers roads, rivers and coastlines, and named floors inside a building.
On also has a fixed use for larger forms of public transport (buses, trains, planes, ships and bicycles) even though you're technically enclosed inside most of them.
- The old town sits on the coast, just south of the harbour.
- Our apartment is on the seventh floor, so the view is excellent.
- I spent most of the journey asleep on the train.large public transport → on
When do you use 'in' for place?
Use in for an enclosed three-dimensional space (a container, a room, a building) and for larger areas such as cities, countries and regions, where you picture yourself as being inside a boundary rather than at a point or on a surface.
Smaller, enclosed forms of transport (a car, a taxi) also take in, which is why cars behave differently from buses and trains in the previous rule.
- The passports are in the top drawer of my desk.
- She grew up in a small fishing village in northern Vietnam.
- We waited in the car until the rain stopped.small enclosed vehicle → in
Same place, different preposition: zooming in and out
The same physical location often takes a different preposition depending on how tightly you're zooming in: at the office (a point), in the building (an enclosed space), on the fourth floor (a level). None of these is wrong; they simply describe the same place from a different angle.
Vehicles are the clearest example of this pattern breaking the 'size' intuition: a bus is far larger than a car, yet a car takes in while a bus takes on, because on is reserved for public transport you can walk around inside, and in for a private vehicle you sit inside.
| Context | Preposition | Example |
|---|---|---|
| Point / address / event | at | at the reception desk, at 10 Downing Street |
| Surface / line / coast / road | on | on the wall, on the coast, on Oxford Street |
| Floor of a building | on | on the second floor |
| Enclosed space | in | in the drawer, in my bag |
| City, country, region | in | in Hanoi, in Brazil, in the Middle East |
| Small, enclosed vehicles | in | in a car, in a taxi |
| Public or large transport | on | on a bus, on a train, on a plane |

Find what is wrong in each one, then open it to check.

Speaking
- Part 2's 'describe a place' task rewards the zoom-in pattern: start broad (in a small town), narrow to a building (at the entrance of the market), then a surface or level (on the second floor); accurate layering of in/on/at signals genuine spatial description skill.
- The car/bus distinction (in a car, on a bus) comes up constantly in Part 1 transport questions; mixing them up is one of the fastest ways to lose an easy accuracy point.
Writing
- In Task 1 maps and processes, describing a fixed layout accurately depends on this system: 'the car park is on the north side of the building' vs 'the reception desk is at the main entrance'.
- In Task 2, when locating an example ('This is common in many major cities'), check whether you mean an enclosed area (in) or a specific institution/point (at a university, at the border) before choosing the preposition.
