I’m Dutch, and the ways autocorrect changes my language, and I guess the German language as well, is not so subtle. We have a rule that when something is one “thing” like a “biophysics group”, we make it one word (Biofysicagroep). But almost any form of autocorrect will split these words. I’m really tired of correcting it all the time and I guess many others with me.
Same for norwegian
Almost all spell checkers will split these examples so it's really changing our language. I have considered filing a bug with Apple because I mostly notice it on my iPhone. Perhaps it's already to late, wrong space use is very pervasive nowadays.
