Prepositions of place describe where something is in relation to other things. They connect a noun or pronoun to another word to show location. In English, the most common prepositions of place are in, on, at, under, next to, between, in front of, and behind. Each preposition has a typical meaning and common patterns of use.

In is used for something inside a space with boundaries. It applies to rooms, buildings, containers, and areas seen as an enclosed space. It is also used for being inside a vehicle or inside a group. The focus is on being surrounded by limits.

in a city	The person is inside the area defined as the city.

On is used for something touching a surface and supported by it. It applies to tables, walls, floors, and any flat or level surface. It can also describe something attached to a surface. The focus is on contact with a surface.

At is used for a specific point or location. It often refers to addresses, events, places of activity, and fixed points. At does not focus on boundaries or surfaces, but on the idea of a spot. The focus is on a precise location.

Under is used when something is lower than and covered by something else. It shows that one thing is beneath another in position. The focus is on being below and possibly hidden or protected by the thing above. It often pairs with on when describing what is above.

Between is used when something is in the middle of two things. Next to is used when something is very close to another thing, often with no gap or a small gap. Both prepositions describe relative position, but between requires two reference points. The focus is on spatial relationships with one or two neighbors.

next to	The object is very close to another object.

In front of is used when something is before another thing from a reference point. Behind is used when something is at the back of another thing from the same reference point. These prepositions depend on orientation and the idea of a front and back. The focus is on relative position along a front-back line.

behind	The object is at the back of another object.

Prepositions of place are usually followed by a noun or noun phrase. The basic pattern is subject + be + preposition + place. Other verbs of location, such as sit, stand, and put, also take prepositions of place. The choice of preposition depends on the meaning, not just the nouns.

Location verbs often use prepositions: She sits in the chair.
The choice of in, on, and at depends on boundaries, surfaces, and points.

Prepositions of place in English include in for enclosed spaces, on for surfaces, at for specific points, under for lower position, between for the middle of two, next to for close position, in front of for before, and behind for at the back. Accurate use relies on understanding the spatial meaning each preposition encodes. Mastery comes from recognizing the typical patterns and the kind of relationship each preposition describes.
