ideal language/Quine/Strawson: here without singular term, extended theory of descriptions, but no subject expression as a genuine proper name - instead subject existence sentences with uniqueness condition - completeness: "There is something that is the only F".
Incomplete: "..dito..., and that..." - then subject/common language: from quantified assertion (also some U-terms) - predicate: if it does not dissolve like this.
