| My limited understanding is that the reality is muddier than them being full fledged languages that originated independently and share only a common written language. That is a Western overused trope. Cantonese seems more a hybrid language akin to English in that it is a blend of Tang Chinese during a migration of Chinese from further north and the language(s) of people already living in that area. The Cantonese description of the entire Chinese ethnic group is literally the Tang people. It applies to all of what is considered subgroups including Teochew, Taisan, Hakka, etc... Cantonese definitely shares similar pronunciations for certain basic words with other Chinese dialects/languages. Also, Cantonese is just one language in the area. There are other dialects that preserve Tang Chinese pronunciation more clearly and are closer to Mandarin. My Chinese surname in my dialect sounds exactly like it would in Mandarin but not in Cantonese. Supposedly Cantonese is actually closer to Tang Chinese than Mandarin because operas/poems from Tang times still rhymne in Cantonese but not Mandarin. This is supposedly due to language drift rather than them not sharing some common ancestry. Think more of the Norman invasion and how German (proto Viet and who knows what else) merged with French (Tang Chinese) to create English... and then suppose England and France would periodically merge and separate instead of splitting apart decisively after the Hundreds Year War. Thus Cantonese and the other similar languages are definitely full fledged but there is also some shared ancestry with Mandarin. Also there is a long, long history of a common written language. People may wish to highlight one aspect or another. Is it English or French if the histories are much more intertwined? Does that question even make sense or is asking that question mostly political? Someone else may have more knowledge of origins of other Chinese dialects/languages. |
Similarly, there is a Sinitic family of languages. But they are as different from one another as any collection of languages that have evolved away from one another, and mixed with other families, over millennia.
It is common for Chinese to believe they can read texts from 2000 years ago because they recognize the signs, but what they think it says has at best a tenuous relationship with what was written.
