Why is there no Cantonese?
I know that there are few people who speak it, but I want to learn it because I currently only know numbers and I think it would be fun to do as well.
Mandarin and Cantonese is both worth to learn. Mandarin is more and more International. Cantonese is only be using in Hong Kong,Macau and two provinces in China called Guangdong (Guangdong means Canton) and a part of Guangxi province (xi=西=west,means west of Guangdong).Cantonese is not easy(harder pronunciation) to learn but it is useful to curse（Yes it is),but it is worth to learn too. You can find funny things in Cantonese and Mandarin. I am live in Guangdong,or Canton now. I know how difficult about pronunciation about Cantonese.
Native Cantonese speaker here! In terms of writing, Cantonese is pretty similar to Mandarin. On the other hand, reading and speaking are totally different, and I wouldn't necessarily go on Duolingo for just speaking.
In China, Cantonese is a language known to people living in the providence. Its unique to its providence. When they go to other provinces they cant understand their unique language but they speak a language in common, Mandarin.
Yes! In fact, Cantonese itself is the common language in that particular providence. At least 50% of Cantonese people don't speak Cantonese at home, we speak our town / village dialogue.
I speak Cantonese as I am from Hong Kong but my proficiency is terrible as I lived almost my whole life in Canada and have little desire to improve on it. It's already requested on Duo from this link: https://forum.duolingo.com/comment/15014194. Duo for some reason doesn't want to make a course for it and the other Chinese languages like Hokkien (Min), Hakka, Shanghainese (Wu) and the other varieties of Chinese are missing as well.
Memrise (website) does have a few lessons. But I agree, it would be awesome to get canto on duo
