Kindle books can be loaned to other Kindle users for a period of 14 days through the Amazon Kindle Store. However, not all Kindle books are eligible for loaning, as this is ultimately up to the publisher of the book. If a Kindle book is eligible for loaning, the option to loan the book will be available in the book's details page on the Amazon website.
To loan a Kindle book, you need to go to the "Manage Your Content and Devices" page on Amazon and select the book you want to loan. From there, you can click the "Actions" button next to the book and select "Loan this title" from the drop-down menu. You will need to provide the email address of the recipient, who must also have a Kindle or the Kindle reading app, and the recipient will have 14 days to accept the loan and read the book.
It's important to note that once a Kindle book has been loaned, you won't be able to access it on your own Kindle device until the loan period is over or the loan is returned early by the recipient. Additionally, not all publishers allow Kindle book lending, so it's possible that some books may not be eligible for loaning.
