A SYNOPSIS OF ROLE AND REFERENCE GRAMMAR 115
this construction the subordinate verb functions as a modifier of the matrix
verb, analogous to the relation between the modifying adverbial subordi
nate clause and the matrix clause in certain types of clausal subordination.
Hence (109a) is an example of nuclear cosubordination and (109b) nuclear
coordination, and both exemplify nuclear subordination.
Examples of RRG projection grammar representations for two kinds
of English core juncture are given in Figures 30 and 31 and for two kinds of
Turkish core junctures in Figures 32 and 33. Figure 30 is an example of core
cosubordination in English. The fact that John is an argument of more than
one core is captured by the theory of control and the linking algorithm to be
presented in section 7.2.1. The constituent projections of these two sen
tences are basically the same, whereas there is a significant difference in
their operator projections: the core nodes are dominated by a superordi-
nate core node in cosubordination (Figure 30) but not in coordination (Fig
ure 31). This reflects the fact that in core cosubordination a core operator
