Why did the Hanseatic League have such a large effect on Danish and Swedish vocabulary?

The significant impact of the Hanseatic League on Danish and Swedish vocabulary was primarily driven by the commercial dominance of Middle Low German between 1250 and 1450. During this period, the league held a near-monopoly on long-distance trade in the Baltic Sea, establishing major commercial hubs in Scandinavian cities that hosted large Low German-speaking populations.12

This extensive contact resulted in a profound linguistic influence, as the widespread use of Middle Low German led to the adoption of a vast stock of loanwords and grammatical formatives in Danish and Swedish. This influence is comparable in scale to the French vocabulary introduced to English following the Norman Conquest. The borrowings were not limited to simple nouns; they included prefixes and suffixes that fundamentally altered the structure of these languages. For example, the Swedish word betala and Danish betale (to pay) are derived from the Middle Low German betalen. This "German middle layer" remains a distinct component of the modern Scandinavian vocabulary, sitting between the native Germanic core and later international loanwords.134
