As it turned out, Roosevelt had things almost perfectly backwards. A century of immigration has done little to dislodge the status of English in North America. If anything, its position is stronger than it was a hundred years ago. Yet from a global perspective, it is not America that is threatened by foreign languages. It is the world that is threatened by English.
Behemoth, bully, loudmouth, thief: English is everywhere, and everywhere, English dominates. From inauspicious beginnings on the edge of a minor European archipelago, it has grown to vast size and astonishing influence. Almost 400m people speak it as their first language; a billion more know it as a secondary tongue. It is an official language in at least 59 countries, the unofficial lingua franca of dozens more. No language in history has been used by so many people or spanned a greater portion of the globe. It is aspirational: the golden ticket to the worlds of education and international commerce, a parent’s dream and a student’s misery, winnower of the haves from the have-nots. It is inescapable: the language of global business, the internet, science, diplomacy, stellar navigation, avian pathology. And everywhere it goes, it leaves behind a trail of dead: dialects crushed, languages forgotten, literatures mangled.
