Are you sure ? “Nie” is the first word that comes to my mind and I think it uses the long i. “Wieder” same thing. Oh, the pronouns “Die, Dieser, Diesen, etc”
Well, perhaps I’m not understanding what you mean by “long i”, but Die etc. are all pronounced with a “dee” sound, as opposed to Die in English. At least, this is what I learned in the five odd years I did German.
A qualquer momento, e com sotaque do nordeste brasileiro, que é um dos mais próximos do sotaque dos portugueses na época das grandes navegações. [;)]
The funny thing about portuguese is how foreigners claim it sounds slavic. I’ve always found that claim weird, until I met 3 polish girls in Norway. I could easily pronounce polish words and they also had a perfect pronounce of portuguese stuff, also a cousin that wen to Eslovaquia claimed that phonetically, eslovaquian sounded very similar to portuguese, I cant help to find that quite amazing.
Mis = the i is a short e, the S is a hard s (sort of sz), the second e is like half an ‘a’ and half an ‘e’ (eh). The second s is soft because it’s terminal.
But if you want an accurate rendering the question isn’t how Germans pronounce German but how did 19th century Galicians like Mises himself pronounce German?
Being German myself, you (the OP) have been pronouncing it just right. Von Mises definitely being a German name (“von” is like “of” in English), it rhymes with the English pronunciation of Jesus.
