I can say "I don't speak [language], sorry." in about 10 languages, just so if someone tries to speak to me I can say that to them.
So far only one person has said any follow up things in that language. I like to think it was "but you're speaking it now!" but probably just about work stuff.
Is it weird that I get a very tiny kick out of the slight confusion I can see on some people's faces?
"I do not speak French" versus "I do not know how to speak French". Both are correct, though only the latter clarifies not speaking the language because they do not understand it, rather than purely out of spite. So in this specific case, the former could be used as a subtle FU.
Wouldnt "je ne sais pas parler francais" be more of a "i dont know speak french"? Like, sounding more gramatically broken?
The 'parler' is in an unconjugated form, i read that like its some broken form hehe
The verb "parler" is indeed supposed to be unconjugated. That's down to differing grammar and syntax in French and English. If I were to try and translate directly from French to English while maintaining the original sentence structure and whatnot, it would look roughly like this:
"I not know not speaking French."
...Which is awkward as hell to read, mostly thanks to French splitting negatives into two parts, but you can see how the verb "parler" (speaking or talking) is unconjugated.
You may also notice how that sentence structure looks more similar to an antiquated way of speaking English, if we tweak that just a little bit:
"I know not how to speak French."
From what I can find and from what I know, it is grammatically correct however French is not my first language. As an English speaker I would probably go "parler le français"
