A recent relaxation of official rules regarding the use of apostrophes in German has caused controversy among grammar sticklers and sparked existential fears about the influence of English. The traditional German practice does not include apostrophes to indicate possession or the genitive case. However, a new rule issued by the Council for German Orthography allows for the colloquial use of the “Deppenapostroph” (idiot’s apostrophe) in certain cases. While some argue that this change reflects the dominance of English, linguists suggest that it may simply be a way to avoid confusion. Despite resistance from language purists, the evolution of grammar rules continues in response to modern linguistic trends.
