The Frankenstein thread prompts this question.
Some people pronounce “stein” in a name as “stine”, and some pronounce it as “steen”. In high school German class we learned that in German, the combination “ei” was pronounced as a long “I” (“aye” or “eye”) and the combination “ie” is pronounced like a long “E” (“eee”).
So if someone’s name is Feinstein, is it “Fine-stine” or “Fine-steen”? It seems to be pronounced both ways. Why?
