Abstract
This paper discusses the concept of government and case-system pro-
posed by Traditional Arab Grammarians, (see Haque (1984), Wright
(1984) and Abdulhamid (1980)). They, basically, regarded the system of
oven morphological realizations and the transitivity theory but not government as
primary factors for it to assign the case of an NP. As- their approach is unable to account for the assignment of the nominative case
without a governor, we opt for case - theory of Chomsky (1995) to solve
this and other problems. X-bar syntax as a module of case theory guarantees
the assignment of case to a DP in the presence of a case - assignor.
The DP must be governed by specific case - assignor in its maximal projection.
This theory introduces the principle of Exceptional Case Marking
as a mechanism that guarantees the assignment of the accusative case by
the matrix verb to the subject of IP under government. In this process. we
depend on the Spec-head relation to achieve this kind of assignment in X-
bar syntax.
