How can you describe what a book is to someone who has never seen book?

Imagine a flat, rectangular object, like a piece of cardboard, but thicker. This object is made of many thin, flat pages stuck together at one edge. Each page is covered in tiny black marks that form letters, which make up words and sentences.

These words and sentences tell a story, share information, or teach you something new. The story can be about anything you can imagine: brave heroes, magical creatures, faraway lands, or even real events from the past.

You can hold this object in your hands, turn the pages with your fingers, and read the words silently or out loud. It's like having a whole world inside your hands, waiting to be explored.

This object is called a book. It's a portal to knowledge, imagination, and countless adventures.
