How did German colonization influence Old Prussian and Latvian vocabulary?

German colonization, which began in the 13th century, had a profound impact on the Baltic languages, particularly Old Prussian and Latvian, through the introduction of numerous direct loanwords.1

The influence was a direct consequence of the social and political structures established by German settlers, merchants, and the Teutonic Order. In these territories, a feudal system emerged where German-speaking elites—including nobility, administrators, and merchants—governed over the indigenous populations. This long-term dominance of German culture and administration facilitated the integration of German vocabulary into the local languages.23

For Old Prussian, the impact was eventually total; the language underwent a process of Germanization that concluded by the early 18th century. Historical records, such as the 16th-century catechisms, reflect this influence, as they were translations from German and often struggled with linguistic accuracy. Similarly, Latvian vocabulary absorbed many German terms due to the centuries-long presence of German-dominated urban centers and the Hanseatic League, which served as a primary conduit for linguistic exchange.421
