Then there is always someone like myself who minics without realizing what I'm doing. When I talk to someone with an accent, I end up returning the same accent in the conversation. I remember the first time my husband heard me do this, he thought was was doing it on purpose. I wasn't and I don't. It just happens.
All brains are wired different.
Languages are so complex and, to add to this, each individual hears then speaks it differently.
German wasn't just one language, either in the late and early 1900s. There are many dialects. My parents' first language was German but they couldn't speak to each other because they didn't speak the same dialect, so, they spoke English in our home.
I know in Russia, when the GR clergy desided that "high[lander] German" was the proper German, there was a turmoil because the majority spoke "lowlander German" and "middlelander German".
I wonder which German dialect was taught the Romanov children.
