Is it really wrong to say "He speaks also French."? I understand it isn't the normal way to say it in English...
You are wright.Even duolingo considers"she also speaks french"correct.
Your understanding is correct.
In English you would say "he also speaks French". Word order is more precise in English I think :-)
So "he speaks also french" is wrong?
In English, yes, it is. You could say, "He also speaks French," or "He speaks French also."
It refers to things, objects, animals ... it is wrong to say "it speaks"
You are wright.Even duolingo considers " she also speaks french " correct.
what's the difference between "pure" and "anche" in sense of "also"? are they both possible in that case?
yes, they are. "pure" is less used, and when used it tends to emphasize the fact that he/she speaks EVEN French :)
