Book excerpt: Languages make us human. The ability to communicate and be understood through songs, art, words, inscriptions, or even gestures is essential because we, as a species, cannot live in isolation. And each one of these languages has its own journey. Early humans leaving messages on cave walls; three men on a raft stumbling upon a language they weren't looking for; a secret language that evolved to hide a people; the world's only undeciphered language that is 4000 years old. The stories in this book take you from the northeastern-most tip of our country to the forests in central India, from indigenous languages that are thousands of years old to those that have developed recently. Engrossing, entertaining, and packed with trivia, this book is for non-fiction lovers and students, who have a keen interest in all things India!
