Agreement
1. If X governs Y,
the features that exist in both X and Y must agree. If the features
do not agree, the form is rendered ungrammatical, which renders
the entire sentence ungrammatical.
2. All features in a projection
of X must agree.
3. All features linked
in a government change must share the same value *(agreement).
Host Requirement
If a feature X requires a specific
category as a host , the form X must be copied to and embedded
in that category, which functions as the host of the feature.
A government link must be established between the original feature
position and the host.
Unspecified Features
3. An unspecified
feature must be assigned a velue (plus or minis in a binary theory.
Feautre Value Condition.
No rule may replace the value
of a feature with another value.
Agreement
Feature Copying to NIL feature
1. If a feature is
marked NIL at A-structure:
a1) copy the feature of
the head to the governee (or)
a2) copy the feature of
the governee to the head.
b1) copy the feature
of the phrase down through each member of the projection if that
feature is NIL.
Affix creation (morphology)
2. If a feature is
marked as [+suffix], the form containing the feature must split
into a stem plus an suffix. The suffix carries the triggering
feature; the remaining features stay with the stem.
Feature Copying to Host
3. If a grammatical
item or lexical form is marked with the feature
[\____]
the feature must be copied to
the closest available host that the category containing the feature
governs. The features in the original position without a host
are deleted as long as a link to the host has been made. Features
cannot be arbitrarily deleted (i.e. realized as the logical form
[NULL]).
The category of the host is
required. If a verb host is required, the feature is written
as
[V\____].
The feature must then be copied
to a verb (host).
Gvoernment here may be called
head government.
Targeting
If an operator is marked as
a target, it must find a traget establishing an antecedent government
link with the target. The features linked in such a chain must
agree.
