Table 7 with Table 8, we see that the order of /a/ and /c/ has switched
n the two cases. This kind of ‘morpheme metathesis’ does indeed occur in
an

orphemes and another morpheme cannot

4.2 Conflicts between Linear C
respondence and other correspondence
r
As we have seen, Linear Correspondence favors a particular orderin
of
phonolo
ical affixes (or /affix/es). Another, potentiall
conflictin
, mappin
principle states which host an /affix/ can attach to. So far, we have implicitly
assumed that any host with which the /affix/ can form a phonological word will do.
In reality, however, an /affix/ usually
ombines with the phonological correspondent
f the head of the category that the morphosyntactic affix (call it
AFFI
combines
with. This condition, formulated in (40), is equivalent to Sadock’s (1991) Strong
Constructional Inte

is phonologically realized as /affix/, and
A comparable phenomenon can be found in En
lish s
ntax. Bobal
ik (2000) shows
hat there are triples
f adverbs occurring in a fixed order that can be broken when only the highest and lowest adverb

ar.
Notice that this anal
sis assum
that the template, rather than Linear Correspondence, is broken up
nto smaller constraints. It is
ossible to achi
e the same result by splitting Linear Correspondence,
but this is somewhat more involved (as it requires
he assumption that the order encountered when all
affixes are present is in fact not the one that is completely in compliance with the template). In
principle, the choice between the two approaches is empirically testable, name
y by considering which
of the orders (the one with all affixes present or
the one with an affix absent) satisfies Linear
orrespondence. We cannot go into this here.
