Ordering is necessary because the change in the order will not derive the
acceptable grammatical form2. If rule (10) is
applied first, then assimilation is not possible because the output of (10)
lacks the environment to bring about the change.

NOTES
|
|
1.
|
Tho data with * do not occur in the actual speech. It represents
intermediate stage when a pair of ordered rulesapply
in a derivation. The form catpa is not derived
by the application of a single rule. Rather it involves the
application of rules (5) and F(12).
|
|
2.
|
Change in the
order will produce form which is unacceptable.
|
|
zgrums + čik |
|
zgrums + ik
(10) |
|
*zgrums + ik (9)
cannot apply |
*zagrumik
does not satissfy the condition required for the
operatinn of rule (9).
|
3.
|
There is no internal
evidence to show that it is the vowel of the suffix that is
deleted. It is possible to formulate the rule in such a way that
the vowel of the stem is deleted.
