in one category vs. the other with respect to the other clause. There is,

then, an "accusative"-like structure, in which Agent-or-Subject in both

clauses co-referent counts as "same", while other conditions count as "dif­

ferent"; there is also an "ergative"-like structure, in which Patient-or-Sub-

ject in both clauses, when co-referent, count as "same", while other condi­

tions count as "different". Notice that other kinds of devices, with privileges of

deletion, anaphorization, etc. also seem to work on similar, global condi­

tions. What is important to see is that the local vs. global nature of the

device depends on how many of the variables of these four domains are left

for coding with some paradigm of specific surface markers in the linked

clause, the variables of one or of two NPs. This is summarized in Figure 7.
