This study explores a number of interrelated issues that contribute to the word order variation in two varieties of Arabic: Modern Standard Arabic (MSA) and Jordanian Arabic (JA). The study adopts recent minimalist assumptions proposed by Chomsky (1998, 2001, and 2005) in order to provide answers for the basic questions surrounding case assignment, subject positions and the agreement patterns shown by the verb in both MSA and JA, in addition to object positions and object movement in MSA.
