I have a book.
This is my book. (my is a possessive adjective)The book is mine. (mine is a possessive pronoun)
What is a possessive pronoun and when do we use them?
Look at this sentence:
This book is my book, not your book.
Here the word book is repeated three times, so it sounds very repetitive.
We already know we are talking about a book so we can replace, my book and your book with possessive pronouns.
We can say:
This book is mine, not yours.
Mine replaces my book.
Yours replaces your book.
Now it doesn’t sound repetitive. It sounds more natural.
Mine and Yours are possessive pronouns.
A possessive pronoun replaces a possessive adjective + noun to avoid repeating information that is already clear.
Look at these sentences:
This is my
These are my
In the second sentence books is plural. Notice how the possessive adjective MY does not change when it comes before a singular noun or plural noun. It is always the same.
How can we change these sentences to include a possessive pronoun? They become:
This is mine.
These are mine.
Again, you can see there is no change.
Possessive pronouns also only have one form. It doesn’t matter if they refer to one thing or more things. They always remain same.
We cannot say: These are mines. This is NOT correct.

Here mine refers to my shoes.
