The exclusive variant
both in its base-driven
and in its affix-driven wording, seems to contain a disguised paradigmatic statement,
ince it implicitly compares -
with rival affixes. Such paradigmatic statements,
according to what we have said in 2.2.1, are the

Plag wanted to get rid of by the in
troduction of base-driven restrictions (
cf. also Plag
2003: 66-67). But in realit
, as we can s

’s account the paradi

creeps back throu

estriction with exclusive ri
hts: but a restriction with exclusive ri
hts is strictl
equivalent to a normal restriction + type blocking. Whether we do it the one way o
he other seems to be a matter of taste. The important thing is that there is no way of
avoiding explicit statements about the pa
adigmatic relationship between rival
patterns.

this simplified statement will do for our purposes). This way of putting things

a
it
ot state explicitly that the negative
estriction is somehow a consequence
f the positive one. Van Marle’s (1986)
omain Hypothesis was specifically designed to avoid this conceptual awkwardness
by postulating a general pri
iple according to which special

eneral domains. Under this h
pothesis, th

ative restriction would no lon

, as we have alread
seen in 2.2.1, the Domain
H
pothesis is untenable. Whether a special domain curtails a
eneral domain or not,
s not predictable but must be stated case by case, either through a combination of
positive restriction + type bl
cking or through a restricti
n with exclusive rights,
which, as we have seen, amounts to the same. In this way we can avoid the explicit
tatement of negative restrictions, something that we would like to avoid fo
principled reasons. As is well-known (c
. Sokolov & Snow 1994 for a good review
f the literature), language learners can
nly rely on positive evidence: they first
earn sin

makin

eneralisations on this
round (c
. Bowerman 1982: 324-328
Pinker 1989). We would thus expect to find no negative affix-specific restrictions in
In the case at hand
it is not clear whether we need
ype blocking or a restriction with exclusive rights at
all, since none of the rival suffixes is a general case (except -
ng
which may not really be
non
mous). If one states the restrictions on the rival suffixes properl
, it ma
turn out that verbs in
do not fall in their domains
so that no paradi
matic statement would be needed.
