In my neighborhood alone, we have families from different parts of China, and a family from Cambodia. (We also have families from Central and South America, and from India). I have classmates at school from all over the world. I'll sit next to people from China, S. Korea, Japan, and Vietnam. And I see on government officials on TV from different Asian countries meeting with one another. Here's my question: How related are the various Asian languages? The Chinese and Cambodian families in our neighborhood speak English to one another, because their native languages do not correlate. I specifically asked them, and that was the answer they gave. (Interestingly, the grandfather in the Cambodian family actually does speak the same Chinese dialect that the Chinese family speaks.) There was a lady from China that sat next to me in a Greek class last semester, and she spoke Mandarin. But there were other Chinese people in the class that she could only speak with in English, because they spoke a different Chinese dialect. I guess I'm wondering if the Asian languages have a common ancestor... sort of like the Romance languages are derivatives of Latin. If so, is that common derivative language dead or still going? I'm just curious.
