You can borrow a book to read or book a room before a trip.

The idea

A book is something you read; its plural is books. Use a book for one unspecified book and three books after a number. As a verb, book can mean reserve: book a room.

Examples

  • I borrowed a book from the library.
  • This book is about birds.
  • Three books are on the table.
  • She reads a book on the train.
  • Please return the library book tomorrow.
  • We booked a hotel room before leaving.
