How do you separate two enchantments in a book in minecraft?

To separate two enchantments in a book in minecraft, you need to use an anvil. First, combine the enchanted book with a plain book to reset the enchantments, but this will remove both existing enchantments. Alternatively, you can use the "Grindstone" to remove all enchantments from a book, effectively separating them if you have multiple books with different enchantments. However, there's no direct way to split enchantments from a single book; you'll need to work with multiple books to achieve your desired outcome.
