What are the types of preposition?

I'm learning this too! It can be confusing. From what I understand, there are a few main types.

There are prepositions for time. These are words like 'at', 'on', and 'in'. For example, "meet me at 8 o'clock" or "on Sunday".

Then there are prepositions for place. These show where something is. Words like 'under', 'behind', and 'in'. Like, "the cat is under the bed".

And there are prepositions for direction. These show movement. Words like 'to', 'into', and 'through'. For example, "she walked to the store".

I think those are the big ones. Hope this helps
