Does anyone know if they are going to be putting out Cantonese or any other Chinese dialects any time soon?
There is currently no Cantonese on Duolingo. At least not now. A post made by RobinCard hinted that Cantonese is coming to Duolingo! My first language was Mandarin and Fuzhou dialect (I learned them at the same time). I think the problem is that the characters are the same, and they would have to branch out from the already existing Chinese tree. Either that or they would have to make an entirely new tree.
The roots of Cantonese language are from Yue which has a longer history than what we know as Mandarin. Actually, the Mandarin that is taught and used now isn't even actually Mandarin. It has been changed and simplified to become the "standard" language of China, Putonghua (the Chinese characters literally mean "normal" language)! Yue and Cantonese can be traced back to Classical Chinese and if you study it, you can see the similarities!
Clozemaster has Cantonese too, but this looked too hard for me. https://www.clozemaster.com/
