Translation:I can't speak Chinese, luckily my friend can.
A: ability in the sense of “know how to” (会 is more common than 能)
B: permission/request (use 能 or 可以)
C: possibility (use 能 or 可以)
D: permission not granted (use 不可以)
E: impossibility (use 不能)
According to this website, 不能说 is correct for A and possibly E also.
"I can't speak Mandarin; it's good that my friends can" should be accepted.
Yeah, same thought here and I think other people in the comments agree... "不能" sounds like something is preventing you from speaking Chinese x) Like, "I'm too drunk right now, so I 不能 speak Chinese" or "I just broke up with my Chinese boyfriend, and Chinese reminds me of him too much, so I 不能 speak Chinese" xD
中文 can refer to Mandarin but it it typically refers to all of the major Chinese languages spoken by the Han Chinese peoples (the majority ethnic group in the PRC/Taiwan) often in written form. When referring to Mandarin itself you'll more typically see things like 普通话 (pǔtōnghuà).
So, the program was correct to reject your translation.
I would like to add a note to the comment from Jason137255 that 会 means "to be able to" in the sense of physical or mental abilities (e.g. to be table to speak a language, swim, drive a car), while 能 means "to be able to" in the sense that you have the opportunity to do it, nothing is preventing you from doing it (so it's possible to 会 but not 能 to do something).
我不可以开车 - I can't drive (because I'm not allowed to, I don't have a driving license)
我不能开车去那边 - I can't drive there (because my mom has my car; because I drank alcohol)
我不会开车 - I can't drive (I don't have the ability to drive a car, I haven't learned it)
我不可以喝酒 - I am not allowed to drink (because I'm under 18)
我不能喝酒 - I can't drink (because I just took some special medicine)
我不会喝酒 - I can't drink alcohol (I'm bad at drinking, I get drunk very easily)
Hope that helps :)
Not quite. According to the Chinese Grammar Wiki (https://resources.allsetlearning.com/chinese/grammar/Comparing_%22hui%22_%22neng%22_%22keyi%22):
"Sometimes they are explained as: 会 means "know how to," 能 means "to be able to," and 可以 means "to have permission to." Actually, they overlap somewhat."
It goes into further details but given what is mentioned in the article I would side with using 能 here.
I sort of feel like this is the difference between English's "Can I" vs "May I".
Wow. I already had questions when I went into this discussion. Now I have ten more! Firstly, according to every breakdown posted above, and also this video,(https://chinesepod.com/lessons/all-about-can-能-neng会-hui可以-keyǐ) where I first learned all this, "可以" doesn't make sense at the end of the Chinese sentence. I didn't even SEE the 会/能 divide at the beginning! Thanks, upstream posters! So our Chinese sentence translates more as "I'm not physically able to speak chinese right now, good thing my friend has permission".
ALSO! What's up with using "中文"? I know there are subtle differences, but I thought "文" referred more to spoken language. Should it not be "汉语"?
From how I was told:
語 just means language
話 means language in a spoken sense, not really including grammar.
文 means language with all it's "scholarly" attributes like grammar, spelling, punctuation etc. and maybe even poetry or calligraphy.
For example, if you tell someone you know 德文, it feels like you've studied German, had classes and exams and stuff. If you say you know some 德國話, it sounds like you've lived in Germany or visited and learned two words or maybe several sentences, or maybe you can actually speak but don't know how to write. Also, a video showing someone speak German would more likely be labeled "德國話" because we're showing speaking; and if it's like an online course or a Youtube teacher it would be 德語 or 德文. Language courses in the university are called "文". The article in Wikipedia about German language is called 德語.
(this is all "reporting" how it is in Taiwan)
Some language do not have a 文. For example, 台灣話 is always 話, it doesn't have a written language. Dialects are 話 - 廣東話, 四川話 (Cantonese is not really a dialect of Mandarin, but you know what I mean, local languages)
Well... I think the distinction is more clear when you say you CAN one of those things, but when you say you can't, it's like, if you can't one you can't another xD Dunno. I don't feel much difference between saying I don't speak 中文 or 汉语. Not a native speaker though :) (lived in Taiwan and learned Chinese for 6 years)
