Contributions to a relative chronology of Persian

Abstract

Old Persian shows a change of postconsonantal y, w to iy, uw, respectively. However, if one applies (pre-)Middle Persian sound changes to the Old Persian forms, the result is at variance with certain Middle Persian forms. If one were to assume a syncope reversing the Old Persian change of y, w to iy, uw, this would also affect old cases of iy, uw and likewise yield incorrect results for Middle Persian. The Old Persian change can thus not have operated in the prehistory of Middle Persian, and there is a dialectal difference between attested Old Persian and the later stages of the language, which is to be added to those already noted. The paper also discusses some sound changes that are connected to the Old Persian change in one way or the other. Cases in point are the processes called Epenthesis and Umlaut in previous scholarship, which this article suggests to interpret as occurring in different contexts and in different periods. The former is limited to Vry, which yields Vir and feeds into a monophthongisation that, as shown by some late Old Persian word forms, occurred within Achaemenid times, giving ēr and īr from ary and əry. Epenthesis did not occur in the prehistory of Parthian, whereas the monophthongisation did. The Appendix presents a tentative sequence of the processes discussed in this article, which is intended as a contribution to the relative chronology of Persian historical phonology.
