"Mittelniederdeutsches Handwörterbuch" by August Lübben is a dictionary published in 1888. This pioneering work captures the Middle Low German language, a vital linguistic bridge in medieval Northern Europe. Drawing from diverse sources including merchant records, legal documents, and literary texts, it illuminates a language that shaped Hanseatic trade and culture from the 13th to 17th centuries. The dictionary serves scholars in linguistics, history, and cultural studies while documenting an essential chapter of German language history.
