Why is the name 'Cleopatra' not allowed in Iceland? Why do clocks 'talk' to the Nahua people of Mexico? And if we are what we eat, are we also what we say? These are just some of the questions Daniel Tammet answers in this book, a mesmerising new collection of essays investigating the intricacies and profound power of human language. Tammet goes back in time to explore the numeric language of his autistic childhood; he looks at the music and patterns that words make, and how languages evolve and are translated.
