The proceedings of FDSL 7, Leipzig 2007, offer current formal investigations into Slavic morphology, semantics, syntax and information structure. In addition to the main conference, FDSL 7 saw the first special Workshop on Slavic Phonology initiated by Tobias Scheer. Some of the papers presented at that workshop are included in this volume as well. The analyses published in this volume address the following Slavic languages: Bulgarian, Czech, Macedonian, Old Church Slavonic, Polish, Russian, Serbian and Serbo-Croatian. FDSL – the European forum for the formal description of Slavic languages – was called into being in 1995. The FDSL-conferences take place biannually in Leipzig and Potsdam.
