What is Reduplication? Typology and Analysis Part 1/2: The Typology of Reduplication

Reduplication has played a central role in the development of phonological theories for 30years. The introduction of Classical Optimality Theory (OT) in the 1990s sparked intensive research into the typology and analysis of reduplicative patterns, as reduplication was a key testing area both for OT and for theories critical of OT. Now, after some 20years of research within the OT model, it is appropriate to assess the leading ideas on reduplication that have come out of this period of concentrated research. This pair of articles serves this purpose. The first article presents a typological survey of the function and form of reduplication, covering classic forms of reduplication as well as less well-studied forms, such as phrasal reduplication, morphologically-complex reduplicants, and reduplication without phonological identity. The second article surveys recent formal approaches, such as Base-Reduplicant Correspondence and Morphological Doubling, covering debates such as the morphological status of the reduplicant, exfixation, semantically empty, a-templatic, and compensatory reduplication.
