This is a course book for advanced scholars in morphology. It provides students and other interested people in linguistics with some morphological tools of analyzing morpho-syntactic structures of different languages. Hence, both students and instructors of morphology will find it quite useful in their endeavors of getting the insights of different morphological variables. The book begins with the architecture of words, i. e.the way words are formed out of smaller meaningful units called morphemes, and ends up with cliticization-pronominalization interface.It is my hope that the contents in all chapters will enrich the theoretical basis of the readers and users.
