In both of these languages, there are constructions in which actor and
potential actor NPs do not receive their canonical morphosyntactic treat
ment, and in some of them they retain their pivot properties and in others
they lose them. The difference turns crucially on whether the constructions
involve preventing an argument that qualifies to be an actor from being
assigned actorhood, a lexical phenomenon in terms of Figure 21, or
whether it entails assigning an actor to a non-canonical (normally
peripheral) syntactic status, a syntactic phenomenon in terms of Figure 21.
Thus the lexical-syntactic opposition, which falls out naturally from the
RRG linking schema in Figure 16, is strongly supported empirically.
5.4 Focus structure and linking
In the linking diagrams in Figures 17-20 the linking procedure appears to
relate the semantic LS representation to a simple LSC syntactic representa
tion, but this is in fact misleading, for it omits a major factor in the determi
nation of the form of the sentence: focus structure. A more accurate rep
resentation of the linking relation is given in Figure 22, which includes all
