Okay kiddo, let's talk about something called "deutschtum". It's a big, fancy word, but it just means "German-ness" or "being German".
So, just like how you might think of yourself as American or Canadian, people in Germany also think of themselves as German. But deutschtum is more than just a label or a nationality - it's a cultural identity, too.
See, there are certain things that people think of as being "German". Maybe you've heard of some of them, like Oktoberfest or schnitzel or even the fairy tales of the Brothers Grimm. These things are all part of deutschtum, because people associate them with Germany and being German.
Deutschtum can also include things like the German language, traditions, and customs. People who feel a strong sense of deutschtum might celebrate German holidays, wear traditional German clothing, listen to German music, or even study the history of Germany to better understand their cultural heritage.
So, overall, deutschtum is just a way of expressing pride in being German and sharing that pride with others who feel the same way. It's kind of like saying "I'm German and I love it!" Does that make sense?
