Thanks again Amy, and thank you Ruby Ruby Ruby Rubeh (lol, sorry, I can't get that song out of my head)
If I got it right, "every" (and similar words, "everything", etc.) is the word to use for what I wnat to say. Ok, I actually already know that...
As for "any" and releted words, they are possible for that meaning as well, but not very common, and they must always be used in a very clear context where it is clear that "not any" is not "no" but "not every, not all, etc."
It it so?
