Empires of the Word: A Language History of the World. Nicholas Ostler

languages have the power to grow in this way? And are there any properties of the relation between the new and the old language which make speakers willing and able to make the leap?

      There is a pernicious belief, widespread even among linguists, that there is a straightforward, heartless, answer to this question. J. R. Firth, a leading British linguist of the mid-twentieth century, makes a good simple statement of it:

      World powers make world languages…The Roman Empire made Latin, the British Empire English. Churches too, of course, are great powers…Men who have strong feelings directed towards the world and its affairs have done most. What the humble prophets of linguistic unity would have done without Hebrew, Arabic, Latin, Sanskrit and English, it is difficult to imagine. Statesmen, soldiers, sailors, and missionaries, men of action, men of strong feelings have made world languages. They are built on blood, money, sinews, and suffering in the pursuit of power.²

      This is above all a resonant cri de cur from 1937, the dying days of the British empire, muscular Christianity and male supremacism; and (in his defence) Firth seems mainly to have been concerned to contrast the effectiveness of lusty men of action with enervated scholars in building international languages.

      Nevertheless it really does not stand up to criticism. As soon as the careers of languages are seriously studied—even the ‘Hebrew, Arabic, Latin, Sanskrit and English’ that Firth explicitly mentions as examples—it becomes clear that this self-indulgently tough-minded view is no guide at all to what really makes a language capable of spreading. It works neither as an account of where all world languages come from, nor what all world powers achieve.

      The best case for it might be thought to come from the examples Firth cites, multinational military empires that lasted for centuries, such as the Roman and British efforts. But although Romance languages are still with us, their common name showing their common origin, they grew up in countries where Roman rule had been stably replaced by Germanic conquerors. The Franks, Burgundians, Vandals and Goths who set up the kingdoms of western Europe after the fall of the empire at most had an effect on the accent with which Latin was spoken and added a few words to its vocabulary; they nowhere succeeded in imposing their language on their new subjects. Yet at the other end of the Mediterranean, the Romans themselves had had no better success in spreading Latin: in 395, despite over five hundred years of direct Roman rule, Greeks, Syrians and Egyptians were still talking to each other in Greek. (Thereafter the empire was divided east from west, and Latin soon lost even a formal role in the east.)

      Farther afield, in the north of China, repeated conquests by Turkish-, Mongol- and Tungus-speaking invaders, who ruled for some seven hundred years out of a thousand from the fourth century AD, had no effect on the survival of Chinese; finally, the Tungus-speaking Manchu conquered the whole country in 1644, and yet within a century their own language had died out. Back in the Middle East, the triumphs of the Arabic-speaking conquerors were only temporary: from the mid-seventh century, their civilisation monopolised Iran, along with its neighbours to west and east, but when the Seljuk Turks conquered the country from the other side in the eleventh century, it became clear that Arabic had never taken root, and the language of everything but religion reverted to Persian.

      Evidently, total conquest, military and even spiritual, is not always enough to effect a language change. Yet at times an apparently weaker community can achieve just this. Consider Aramaic, the language of nomads, which swept through an Assyrian empire still at the height of its power in the eighth century BC, replacing the noble Akkadian, which went back to the very beginning of Mesopotamian civilisation. Or consider Sanskrit, taken up all over South-East Asia in the first millennium AD as the language of elite discourse, even though it came across the sea from India backed by not a single soldier. It even appears that Quechua, which became the language of the Inca empire in Peru in the fifteenth century, had actually been adopted as a dynastic compromise: the rulers gave up their own language in order to secure orderly acceptance of a vast extension of their power.

      Economic power, often believed to lie at the root of the spread of English, whether under British or American sponsorship, seems even less coercive than the military. Phoenician shipping dominated the trade of the Mediterranean for most of the first millennium BC; for much of that time, it was backed up in the west by the dominance of the Phoenician colony of Carthage, which spoke the same language. But the Phoenician language seems to have remained unknown outside its own settlements: Greek was the lingua franca for international discourse, used even in the Carthaginian army. Farther east and later on, in the sixth to eighth centuries AD, the queen of the Silk Roads to China was the Iranian city of Samarkand: its language was Sogdian, but who has heard of it? Sogdian merchants, rich as they were, found it politic to use the customers’ languages—Arabic, Chinese, Uighur-Turkic and Tibetan.³

      In that muscular quote, Firth had emphasised the religious dimension of power, and this is often important: perhaps, indeed, we should be talking not of language prestige but language charisma. Sanskrit, besides being the sacred language of Hinduism, has owed much to disciples of the Buddha; and Hebrew would have been lost thousands of years ago without Judaism. Arabic is more ambiguous: in the long term, Islam has proved the fundamental motive for its spread, but it was Arab-led armies which actually took the language into western Asia and northern Africa, creating new states in which proselytising would follow. Arabs were also famous as traders round the Indian Ocean, but the acceptance of Islam in this area has never given Arabic anything more than a role in liturgy. Curiously, the linguistic effects of spreading conversions turn out to be almost independent of the preachers’ own priorities: Christians have been fairly indifferent to the language in which their faith is expressed, and their classic text, the New Testament, records the sayings of Jesus in translation; and yet Christianity itself has played a crucial role in the preservation of, and indeed the prestige of, many languages, including Aramaic, Greek, Latin and Gothic.

      In fact, proselytising religion has been a factor in the careers of only a minority of world languages. It could be claimed that religion is just an example of the cultural dimension of language, which represents the ultimate source of language prestige. Culture, of course, is an extremely vague word, covering everything from the shaping of hand-axes to corporate mission statements, as well as the finer appreciation of the sonnets of Shakespeare and the paintings of Hokusai; so its relevance will need considerably closer attention.*

      In the analysis of prehistoric movements of peoples, and the apparent ruthlessness with which one comes to replace another (as in the Bantu-speaking peoples’ spread across the southern third of Africa, with consequent restriction of the domains of the San and Khoi; or the penetration of Austronesian sailors into South-East Asia and into contact with Melanesians), there is little reluctance to discuss the cultural factors presumed to have given the advantage. Finer arts and higher learning are not usually considered serious contenders. Cultural factors that enhance the ability to support larger populations (for example, by new forms of farming or husbandry) are deemed especially important. But simple innovations in military practice may also be effective.

      Occasionally, brute biology takes over, and mere cultural differences are left on the sidelines, for a time irrelevant. If a population was vastly more liable to die from disease, as were the invaded inhabitants of the New World facing European interlopers in the sixteenth century, it hardly mattered that their weaponry and military tactics were also vastly inferior—or by contrast that the vegetables they cultivated (including potatoes and maize, tomatoes and chocolate) turned out to be world-beaters.

      But the search for the causes of language prevalence is not usually so easily resolved. In the historic record of contacts between peoples, and contests between languages—when we have eyewitness testimony to keep us honest about what really went on—we often cannot point to cultural differences that were clearly crucial. Then we may have to look deeper: not just into the perceived associations of the different communities, how they looked to each other, the language communities’ subjective reputations as well as their objective advantages, but even—and this is deeply unconventional, especially among linguists—to the properties of the languages themselves.

      Bizarrely, linguists
