What is the difference between 'at the store' and 'in the store'?

At the store treats it as a general location or destination. In the store focuses on being inside the building. Both are correct; choose the one that matches the meaning you want.

Is it 'in the street' or 'on the street'?

For a general street location, American English usually says on the street, while British English often uses in the street. Context can affect the meaning, but this guide uses the common American form.

Why do you say 'in the car' but 'on the bus'?

English treats these as fixed combinations: in the car and in a taxi, but on the bus, on a train and on a plane. Being able to stand and walk around is a useful memory aid, not a complete rule.

Grammar Level A2

Prepositions of Place: At, In, On

At a point, in an enclosed space, on a surface — the idea behind at, in and on for place, plus the fixed phrases that break the pattern, and an exercise.

at the door · in the room · on the table

Three little words, three useful mental pictures. At often treats a place as a point or general location. In often places something inside an area or space. On often places it on a surface or line. These pictures explain many uses; fixed phrases and context cover the rest.

At — a point on the map

Use at when you view the place as a point or general location. It is common with meeting points, events, workplaces and numbered addresses.

at home · at work · at school · at the bus stop · at the door · at the airport · at a party · at 42 Oak Street

I'll meet you at the station at six. · She's at work until five. · There's someone at the door.

Note at home, at work, at school — no the. These are among the most useful fixed phrases in the language, and adding an article is one of the most common learner slips.

In — inside something

Use in when you view something as an area or enclosed space — a room, building, city or country. Some combinations, such as in bed, are best learned as fixed phrases.

in the kitchen · in the car · in a taxi · in bed · in the garden · in Paris · in Brazil · in my pocket

The kids are in the garden. · He grew up in Brazil. · My keys are in my pocket.

At vs. in for the same building. Both can be right — they just frame it differently.

I'm at the supermarket. (where I am — the usual choice)
It's cold in the supermarket. (the space inside)

On — a surface, a line, a large vehicle

Use on for things resting on a surface — and, by extension, for lines (streets, rivers, coasts) and for vehicles you can stand up in.

on the table · on the wall · on the floor · on the second floor · on the bus · on a train · on a plane · on the coast · on Oak Street

Your phone is on the table. · We live on the third floor. · I'll call you when I'm on the train.

The vehicle combinations are worth memorizing as pairs: in the car / in a taxi, but on the bus / on the train / on the plane. Being able to stand and walk around is a useful memory aid for on, not a rule that predicts every expression.

Common mistakes

Adding the to at home. The fixed phrases don't take an article.

✕I stayed at the home yesterday.
✓I stayed at home yesterday.

Using in for a large vehicle. Buses, trains and planes take on.

✕I met her in the bus this morning.
✓I met her on the bus this morning. (but: in the car, in a taxi)

Using in for a city you're arriving at. With arrive, cities and countries take in, but buildings and stations take at.

✕We arrived in the airport at eight.
✓We arrived at the airport at eight. (but: we arrived in Chicago at eight)

Use on when naming a floor of a building.

✕Our office is in the fourth floor.
✓Our office is on the fourth floor.

One dialect note rather than a mistake: on the street is standard in American English, in the street is common in British English. Neither is an error — just don't switch between them inside one text.

Quick exercise
