I'd like to ask about the usage of they are with things/objects. Is the meaning the same as two other sentences? Can they are replace those are/these are with no difference in meaning? If not, what's the difference? I know that These are/Those are are used depending on how far the object is located.
They are books.
Those are books.
These are books.
To clarify, I'd like to give an example.
They __________ books.
Of course the answer is They are books.
If I replace the example with the sentence: These are books., would the meaning remain the same as They are books.?
I guess that "they are" is neutral and can mean the same as these are/those are.
What do you think?
They are books. = These are books. in this example? (books are near me) They are books. = Those are books. if the books are far from me.
