Prepositions

Something is above something else if it is higher up.

In the picture, the dog is looking down from the balcony above.

Something is behind you if you cannot see it - your back is facing it rather than your front. The horse in the picture is viewed from behind.

Two things are beside each other if they are next to each other, facing the same direction. The two women on the bench are sitting beside each other, or side by side.

By might mean near, as in "she was sitting by the lake".

It might also be used to indicate who did something, for example "this book was written by my brother".

For means with a purpose of, or intended to belong to. Some examples are:
"I am collecting shells for my sandcastle"
"That cupboard is for the towels"
"Is that for me?"
Not to be confused with four.

You like something if you find it enjoyable. Most people like chocolate, they like their pets and they like their friends. The boy in the picture likes icecream. When you really really like someone or something, you can say you love them.
Like is also another word for similar or alike.

Something is off if it is not powered up and available to be used. The computer in the picture is switched off.
Off also can be used to indicate something no longer attached to something else: "the branch broke off the tree", or for reducing something: "take ten percent off the price".
The opposite of off is on.

The opposite of out is in.

Over is when you move above something. The soldiers in the photo are climbing over a wall.

You go through something when you go in one side and out the other.
The little girl in the picture is going through a hole in a playground.
