Fields of interest

  • Dutch: etymology, historical linguistics, dialects
  • Old Germanic
  • Albanian
  • The linguistic history of Latin
  • Ancient Indo-Iranian languages
  • Comparative Indo-European reconstruction



For the last five years, I have been Principal Investigator of 'The Dawn of Dutch', a five-year project funded through the Vidi-scheme of the Dutch Organization of Scientific Research (NWO). The project aims to explain the rise of Dutch as a linguistic entity, separate from Frisian and German. The main hypothesis is that language contact processes, in particular with Frisian in the western Low Countries, were of major importance for the development of Dutch. The main focus of my own research in this project is to determine which elements of Dutch grammar can be ascribed to contact with Frisian, and which cannot. Other research projects are concerned with a variety of subjects in the history of the Indo-European languages, such as Albanian, Germanic, Greek, Indo-Iranian, and Latin, with a focus (hitherto) on phonetics, phonology and morphology. In general, any archaeological, historical or geographic fact that sheds light on linguistic data from the Indo-European language has my attention.


Teaching activities

I teach courses at all levels of the BA and MA linguistics. Subjects are (1) more general and theoretical courses on language change, historical reconstruction, dialectology; (2) more specific courses on the philology and linguistic history of many ancient Indo-European languages, such as Albanian, Ancient Greek, Avestan, Latin, Lithuanian, Old Irish, and many Old Germanic languages; (3) introductions and advanced courses in the reconstruction of Proto-Indo-European. I regularly (but not every year) teach at the Leiden Summer School in Languages and Linguistics. At this moment (2014) I supervise the following PhD students: Borana Lushaj (on language contact between Albanian and Southern Italian dialects in southern Italy); Alexander Schwager (on the graphemics and internal layering of the so-called LeidenWilleram, a partly Old Dutch text); Sima Zolfaghari (a grammar and lexicographic study of Bakhtiari, a modern West Iranian language). I will be glad to take on new PhD students in the fields of my expertise. I also encourage BA and MA students who are considering a thesis on the history of Dutch, or on one of the other subjects mentioned above, to request my supervision

Media and education

In 2011, I was interviewed in a TV series on the Dutch language. Topic of the episode was ‘How did Dutch sound 1,000 years ago?’ In the programme, two famous Flemish actors impersonate two speakers of Old and Middle Dutch. See http://www.canvas.be/video_overzicht/64324. The Dutch pop singer Spinvis remixed my text into a new song, see Youtube video below. In 2010, Alexander Lubotsky and I edited the booklet Van Sanskriet tot Spijkerschrift.Breinbrekers uit alle talen (Amsterdam University Press), which contains fifty assignments from previous linguistic olympiads, and which can be used by school teachers and students to train for the competition. In 2007, I took part in a dialectological field trip to northern Albania. See www.balcanicaucaso.org/ita/aree/Albania/Bocca-occhi-orecchie for a report. A dvd which can be used for educational purposes was also made.
