Asking such a question in this theory is rare,because to cover the whole skeleton of this question with substantial flesh is not a simple deal.But yet the paper attempts this question indirectly by discussing such central issues:(a)“grammar”in Distributed Morphology,(b)“morphology”in Distributed Morphology,(c)what is Distributed Morphology?(d)what has been Distributed?(e)why Distributed Morphology?(f)post-syntactic operations in Distributed Morphology,(g)key features of Distributed Morphology,(h)current issues of debate in Distributed Morphology,(i)analysis of some words from Hausa in Distributed Morphology.Discussion and explanation of the above mentioned issues will give clear picture of Distributed Morphology theory.
