Side-by-side comparison
In
preposicion de lugar"In" indicates that something is inside a space. Cities, countries, and enclosed spaces take "in". Also transport when you travel inside it.

On / At
preposicion de lugar"On" is for surfaces and transport you travel aboard. "At" is for a specific point: a stop, an address, a building by its function ("at school", "at work").

Common mistake
The most common mistake: "on the car" when you are inside. It is "in the car". But journey transport uses "on": "on the bus", "on the train". And "on the wall" = on the surface; "in the wall" = inside the wall.
Trick to remember it
- •"In" = the space surrounds you in 3D (cities, rooms, closed vehicles).
- •"On" = contact with a surface or journey transport.
- •"At" = a specific reference point (the entrance, the corner).
Quick rule
- •"In" = inside a 3D space.
- •"On" = on a surface or in journey transport.
- •"At" = at a specific reference point.
Did you know?
The "on the bus / in the car" rule is one of the most discussed English irregularities. The historical explanation: public transport (bus, train, plane) is conceptualized as a journey mode, you board, travel, disembark, and uses "on", just like "on a journey". Private vehicles are conceptualized as enclosed spaces and use "in". In informal American English, "in the train" and "in the plane" are increasingly heard, suggesting the distinction may level out over time.
