Prepositions of Place

Prepositions can be used to show where something is located.

The prepositions at, on, and in

1. We use at to show a specific place or position.

For exemple:   Some is at the room

     2. We use on to show position on a horizontal or vertical surface.

For exemple:: the pencil is on the desk

     3. We also use on to show position on streets, roads, etc

For exemple:  I used to live on Portland Street.

     4.We use in to show that something is enclosed or surrounded.

For exemple: The dog is in the garden.

    5. We also use in to show position within land-areas (towns, counties, states, countries, and continents).

For exemple: I used to live in Nottingham.
