What is the difference between On and In(prepositions of place)?
In general, we use on for surfaces and in for enclosed areas(Inside and outside!.
Let’s look at more examples:
On
I am sitting on the floor.
I am lying down on the bed.
Put the picture on the wall.
I watch Game of Thrones on T.V
I will send you a message on Whatsapp.
For everything online, we use on because the screen of your computer or cellphone is a surface.
In
I work in a big building.
I went for a walk in the park.
I put the tea in the cup.
The ball was in the net.
She put the ring in the cake.
Remember that we use in for volumes/areas. That is why we use in for parks because we think of the area of the park on a map. The same logic applies to a neighbourhood.
