Alwin Kloekhorst

Alwin Kloekhorst (born 1978) is a Dutch linguist, Indo-Europeanist and Hittitologist. He was appointed a full professor in Anatolian Linguistics at Leiden University in November 2023.

Kloekhorst received his Ph.D. in 2007 at Leiden University for his thesis on Hittite. In over 1200 pages, his dissertation describes the history of Hittite in the light of its Indo-European language origin. Part One, Towards a Hittite Historical Grammar, contains a description of Hittite phonology and a discussion of the sound laws and morphological changes that took place between the Proto-Indo-European and Hittite. Part Two, An Etymological Dictionary of the Hittite Inherited Lexicon, contains etymological treatments of all Hittite words of Indo-European origin. One of the dissertation's most important conclusions is the confirmation that the Anatolian languages split from Proto-Indo-European before all other Indo-European branches, which have undergone a period of common innovations (see Indo-Hittite). The thesis was published in the Leiden-based Indo-European Etymological Dictionary project.
