your sentence was asking him if he was speaking english. those were obviously english words. there's a statement for everything, and there's also a wrong statement for everything.
make the right choices; make the right statements :-)
I swear something is wrong with the way you understand stuff. Yes, I asked if he was speaking English, but your previous post had the misconception that I did not
understand it, and I said I did understand it. I then pointed out, again, his inability to English.
Also, just because English words were used in a sentence doesn't mean the language that the sentence is written is is still English. Languages (especially language groups/families) are typically defined as having different grammatical structures, such as the French language using adjectives like color after the noun they describe. In the sentence "The English you are be speaking?", the grammatical structure is different than English. So though the words are the same, the language can be defined as not English. And indeed it is not.
