At, In, On: Prepositions of Place

Location, Location, Location (But With Grammar)

Right, same three words, different job. Now they're telling us where things are instead of when. Think of them as your GPS for grammar - except they actually work properly.

The Location Trinity:

AT = specific points and addresses

IN = enclosed spaces and areas

ON = surfaces and lines

Preposition	Used With	Examples
AT	Specific points, addresses, events	at home, at the station, at the party
IN	Enclosed spaces, countries, cities	in the room, in London, in the car
ON	Surfaces, floors, streets	on the table, on the floor, on Baker Street

AT - For Specific Points (Pin It on the Map)

Use AT with:

Addresses: at 25 Oxford Street, at my house
Specific locations: at the bus stop, at the corner
Events: at the concert, at the meeting
Institutions: at school, at university, at work
Activities: at the cinema, at the gym

IN - For Enclosed Spaces (Inside Something)

Use IN with:

Rooms: in the kitchen, in the bedroom
Buildings: in the hospital, in the office
Vehicles: in the car, in the taxi (but "on the bus/train")
Countries/Cities: in France, in Manchester
Areas: in the garden, in the park
Water: in the sea, in the river

ON - For Surfaces (Something's Touching)

Use ON with:

Surfaces: on the table, on the wall
Floors: on the ground floor, on the second floor
Streets: on High Street, on the main road
Public transport: on the bus, on the train
Islands: on the Isle of Wight
Body parts: on my hand, on your face

Confusing Cases (The Ones That'll Trip You Up)

Pay attention to these tricky sods:

at home vs in the house (home = concept, house = building)
in the car vs on the bus (cars are private, buses are public)
at the corner vs on the corner (both correct, slightly different meaning)
in the street (British) vs on the street (American)
at work vs in the office (work = activity, office = place)
