Novelist and "Life of Pi" author Yann Martel has lived a life of travel and multilingual adventure. Nothing opens the mind like travel, he says, and nothing defines the self, or how we relate to one another, quite like language. Martel adroitly compares the linguistic practices of different nations, noting how the French are often hungry to adopt English words, but French Canadians resist such intrusion. And he dispels linguistic myths, such as the Inuit having more words for "snow" than other languages. Trilingual himself, Martel gives an insider's account of this fascinating topic.
