Use

At, in, and on can be used with place words to show where something happens. We use specific prepositions of place to describe the positions of nouns.

Example:

Tom is in the park.

Explanation:

We use the preposition in to say where Tom is. The park is Tom’s current location.

How to build

Prepositions of place at, in, and on go before the word for the location. This is how we create a prepositional phrase using the prepositions of place at, in, and on:

at/in/on + article + location noun
