"Soll die plattdeutsche Sprache gepflegt oder ausgerottet werden? Gegen Ersteres und für Letzteres" is an important work of the German writer Ludolf Winbarg, in which he considers the problem of the preservation or extinction of the Nizhny German language. The author reasonedly expresses his position "against the preservation" of this language, believing that it has already exhausted its historical purpose and has no prospects in the future. The book contains many interesting arguments and analyzes that encourage readers to deeply discuss the topic of language development and preservation of cultural heritage.
