Leiden Indo-European Etymological Dictionary Series

The Leiden Indo-European Etymological Dictionary Series publishes the results of a major Leiden University project identifying and describing the common lexical heritage of the Indo-European languages. Under the supervision of Alexander Lubotsky, an international team of historical linguists has for more than a decade researched, collected and integrated a growing corpus of linguistic data. The data is published in a series of etymological dictionaries and will be concluded by the publication of a large Indo-European Etymological Dictionary, deemed as a successor of Julius Pokorny’s standard work published in 1959.

The Leiden Indo-European Etymological Dictionary Series is also available online.
Indispensable for all those interested in historical and comparative linguistics, as well for those interested in any of the languages dealt with.
