Etymology
Origin of book
First recorded before 900; Middle English, Old English bลc; cognate with Dutch boek, Old Norse bลk, German Buch; akin to Gothic boka โletter (of the alphabet)โ and not of known relation to beech, as is often assumed
Explanation
For a lot of kids, "Harry Potter and the Sorcerer's Stone" was their first experience of really falling in love with a book, or a collection of printed words or illustrations bound together. Book is a widely-known word with a whole lot of less well-known meanings. The noun book can refer to a bunch of pages bound together, as in a book you read, but also a book of tickets or stamps, a section of a larger work of literature (like a book of the Bible), or the written script of a stage play. Book can also be a verb meaning "to record information about a criminal suspect" or "to reserve," which you could use to say, "Let's book a room at the nicest hotel in Maui this winter."
