> I think we are in agreement. There are two definitions of ambiguity in play here. There is logical ambiguity, which I want to eliminate, in which a sentence can be parsed in multiple, contradictory ways. And then there is ambiguity due to imprecision, in which words have broad meaning and without context or clarification a given sentence parsed to a single logical statement can nevertheless have multiple distinct interpretations. That's ok.

Yeah, I can agree with all of this. (Although Anna Wierzbicka’s work on the ‘Natural Semantic Language’ is an attempt to control the latter sort of ambiguity… you might find it quite interesting, actually.)
