Introduction
The vast expanses of the Eurasian Steppe have historically served as the connective tissue between the dominant civilizations of the East and West. While much scholarship has focused on the military and political movements across these plains, the linguistic medium of these exchanges remains a fertile ground for diachronic inquiry. Trade, by its very nature, necessitates a shared semiotic system, often resulting in the birth of pidgins or the elevation of specific dialects to the status of a lingua franca.
Our analysis begins with the late Mongol era, where the "Pax Mongolica" created a unique environment for cross-pollination. The administrative records of the Golden Horde reveal a fascinating blend of Turkic syntax with Persian and Arabic administrative vocabulary, forming what we define as the "Steppe Chancery Vernacular."
Methodological Framework
To map these shifts, we utilized a computational philology approach, scanning a corpus of over 2,500 documents. We tracked the frequency of loanwords and grammatical transformations across three distinct temporal windows: the Post-Mongol fragmentation (1360–1500), the rise of the Gunpowder Empires (1500–1750), and the era of Modern Imperialism (1750–1880).
The Role of the Caravan Cities
Cities like Samarkand and Astrakhan acted as linguistic crucibles. It was within the marketplace (bazaar) that the most rapid shifts occurred. Merchants from the Russian principalities, the Ming dynasty, and the Safavid Empire developed a pragmatic "Bazaar Turkic" that stripped away complex morphology in favor of a streamlined, highly functional communication tool.
This vernacular was not static. As the 17th century progressed, we observe an increasing "Sinitic" influence in the eastern regions of the steppe, while the western borders began incorporating French and German terms related to navigation and scientific instruments, reflecting the shifting centers of global economic gravity.
