Sells (1985:25) and Cook (1988:33)
In the diagram above, no part can be considered in isolation from the
rest. Government and Binding theory posits seven sub – theories of the
theory of grammar. The structure generated at various levels is
constrained by a set of theories, which define the kind of relationships
possible within a grammar. The sub – theories of Government and Binding
theory are:
i. X – BAR THEORY
ii. THETA THEORY
iii. CASE THEORY
iv. BINDING THEORY
v. BOUNDING THEORY
vi. GOVERNMENT THEORY
vii. CONTROL THEORY
1.8.1 X – BAR THEORY
X – bar theory is part of the grammar that regulates and brings out
what is common in the structure of phrase. Cook (1988:94) says:
“In the X – theory, the phrase structure is a comparatively simple
system derived from a few principles and the setting of certain
parameters.â€
A phrase always contains a head in X – bar theory
thereby showing hierarchy among the constituents. Heads are terminal
nodes that dominate words.
According to Haegerman (1991:105),
two levels of projection are distinguished in X – bar theory. These are
the specifier and complement positions respectively.
X â€
(Specifier) X ’
X (complement)
FIG 1.2: X-Bar theory (Radford 2002:229)
X
’’ above ranges over all phrasal categories like Noun phrases, verb
phrases, adjectival phrases, prepositional phrases, inflectional phrases
and complementizer phrases.
X’ on the other hand stands for x
and its complement where applicable. ‘X’ is a category variable that
stands for any major word – level category like Noun, verb, adjective
and preposition.
