Question to Germans, Swiss, and Austrians
So my German teacher is around 60 years old, good lady. She's from very southern Germany. Is there anything that she could be teaching that's not used anymore amongst young people?
Germany had a spelling reform in the '90s and then a reform to the reform a couple of times later on. https://en.wikipedia.org/wiki/German_orthography_reform_of_1996
Other than that the German vocabulary is evolving just like any other language. Words not used anymore are for example
"Fräulein" - "Miss"
"Kegel" - a child born out of wedlock
