You use back with an intransitive verb to say that someone returns to a place where they were before.
In conversation, instead of saying that someone will 'come back', you often say that they will be back.
Be Careful!
You never use 'back' with the verb return. You do not say, for example, 'He returned back to his office'. You say 'He returned to his office'.
You use back with a transitive verb to say that someone or something is taken or sent to a place where they were before. Back usually goes after the direct object.
When the direct object is a pronoun, back always goes after it.
However, when the direct object is a long noun group, or a noun group followed by a relative clause, you put back in front of the noun group.
Back can also be used to say that someone or something returns to a state they were in before.
Back is also a noun. Your back is the part of your body from your neck to your waist that is on the opposite side to your chest and stomach.
The back of an object is the side or part that is towards the rear or farthest from the front.
The back of a door is the side which faces into a room or cupboard.
The back of a piece of paper is the side which has no writing on, or the side which you look at second.
Note that in British English you do not talk about the 'back side' of a door or piece of paper. However, in American English, this construction is common.
