Move away from the regular tourist routes, however, and English soon becomes conspicuous by its absence. It is important not to forget the fact that, even if one third of the world is now regularly exposed to English, as was suggested in chapter 1, this still means that two thirds are not. We need only to walk up a side street in a city, or pause at a village on our way to a destination experience the world's remarkable linguistic diversity. The more we know about the language(s) of the country we are exploring, the more we shall be rewarded with a visit that is insightful and comfortable.
