stop. Surface realization (4) is based on NAG (b) and continues with an arc
1 traversal to produce bone , a 2-3 traversal to produce dog , and an arc 4
traversal to produce the full stop.
Surface realizations (5) and (6) are based on NAG (b). They share a 0-1
traversal to realize bone . (5) continues with an arc 2 traversal to produce find ,
an arc 3 traversal to produce dog , and an arc 4 traversal to produce the full
stop. (6) uses an arcs 2-3 traversal to produce dog andanarc4traversalto
produce find_.

7.5 Transparent vs. Opaque Functor-Argument

The elementary signatures in 7.3.6 are called transparent because the corre-
sponding combination of proplets uses their original lexical form, without
having to add new attributes for coding the semantic relation in question.
The treatment of subclauses in NLC'06, Chap. 7, however, requires also V / x V

(subject sentence), V \ x V (object sentence), V | x N (sentential adnominal modi-

| x V (sentential adverbial modifier) relations. 20
Consider the following signatures of extrapropositional functor-arguments in
comparison with their intrapropositional counterparts: 21

fier, a.k.a. relative clause), and V
