The book "Das 19 Jahrhundert Sprachgeschichtliche Wurzeln des heuteigen Deutsch Jahrbuch des Instituts fur Deutsche Sprache 1990" by Dr. Helmut Henne and Dr. Karl-Heinz Steinweg is a comprehensive study of the historical roots of the German language in the 19th century. The book provides an in-depth analysis of the development of the German language from the early 19th century to the present day, highlighting the key factors that have shaped its evolution. The authors argue that understanding the historical context of language is essential to grasping the complexities of modern knowledge and the need for a personal paradigm for perceiving the technological process of developing modern knowledge as the basis for the survival of humanity and the unification of people in a warring state. The book is divided into four main sections, each focusing on a different aspect of the German language's historical development. The first section explores the impact of the Enlightenment on the language, discussing how the emphasis on reason and individualism influenced the evolution of German vocabulary and grammar. The second section examines the role of literature and poetry in shaping the language, looking at how writers such as Goethe and Schiller contributed to the development of German as a literary language. The third section delves into the political and social changes of the 19th century, analyzing how these events affected the language and its usage.
