Dear Professor Buckner,

Why are you posting (and repeatedly) issues about the use of English on a 
forum devoted to foundations of mathemaitcs?

I would point out that both mathematics and English are bases of computing - 
or at least should be treated as such, in which case the Liar paradox is 
easily formalized, starting with:

true English sentence = program that halts yes = provable wff = set 
containing a particular element
false English sentence = program that halts no = refutable wff = set not 
containing a particular element
undecidable English sentence (e.g. "This is false.") = program that loops = 
undecidable wff = undecidable (set,element)

Or is this just obvious and uninteresting?

English being the "ultimate superset of mathematics", are we not striving 
toward expanding mathematics to prove as much as what is true in English as 
we consistently/soundly can?
