Type II NI is a natural extension of Type I. As in Type I, IN's lose their syntactic status as arguments of the clause; and they are unmarked for definiteness, number, or case. This does not necessarily mean that they are indefinite or non-specific, but only that they are unmarked. [...] Type II NI goes further than Type I, however, in having an effect beyond the V itself. Instead of simply reducing the valence of the V by one, it permits another argument of the clause to occupy the case role vacated by the IN. The result is a lexical device for manipulating case relations within clauses.
