Prepositions are the words in a sentence that tell us the position of something, when it’s happening, or the direction it’s going.
Position: these include on, under, behind, in front of, next to, inside.
For example: The cat is under the table.
When: these include before, after, during, on Saturday.
I’m going shopping on Saturday.
Direction: these include towards, away from, along, into.
Mikey walked along the road.
This term is quite easy to remember because preposition has position in it!
