Daniel Tammet, author of the bestselling memoir Born on a Blue Day, here draws on his own experiences as an autistic person and a polyglot to explore what the intricacies and oddities of human language can teach us about ourselves. His 15 essays cover such topics as the art of translation, sign languages, the music and patterns of words, the grammar of telephone conversations and the rules that prescribe acceptable Icelandic names. Slightly off-mint.
