Okay kiddo, so Meir Ashkenazi is a merchant. That means he buys and sells things, just like you might trade toys with your friends. But instead of toys, Meir might sell clothes, food, or anything people want to buy.
Now, Meir is a bit different from other merchants because he is from a group of people called Ashkenazi Jews. They are a group of Jewish people who come from Central and Eastern Europe. This means that Meir might have a different language and culture than other merchants.
But no matter where he comes from, Meir works hard to make sure his customers are happy and that he gets a good price for the things he sells. He might even travel far distances to find the best items to sell in his store.
So, in a way, Meir is kind of like a grown-up version of you when you play pretend store. Except he actually gets paid for it!
