Natlangs typically relies on propositional logic *as well as* other
forms of logic by which that kind of alignments are realized. I'm not
an expert logican or linguist but I do understand that such
propositional expressions as "A is B" is prevalent in natlangs while
numbered place structures are not. So at least I've been tempted to
think natlangs commonly share the logic of proposition as one of their
basic components. Please fix my bug if any.
