This volume offers papers that emerged from the meeting of the International Syriac Language Project (ISLP) which took place at Stellenbosch University, South Africa, in September 2016, and at the Humboldt-Universitat zu Berlin, in August 2017. The ISLP invites research not only into Syriac, but extends its range to all ancient language lexicography. Hence its proceedings enrich the whole field of Syriac, Hebrew, and Greek lexicography. The ISLP especially encourages research into the interfaces between these languages, and hence the current volume contains a number of papers on translation equivalence: Hebrew-Greek, Hebrew-Syriac, and Greek-Syriac. Other philologically focused pieces explore matters relating to textual and manuscript traditions. All of these are preceded in the present volume by an extensive review of the production and achievements of the ISLP to date.
