What do you mean by standard meaning? Do you mean, the meaning we
learn by learning ordinary English?

What a silly question.

There's nothing silly about the first question. You obviously mean
something other than the dictionary definitions of the words; so what
is it?


Then 'every A is B' and 'no A is
B', as 'every' and 'no' are commonly understood, they cannot both be
true.
