The conception of this volume goes back to the 2010 Sound of Indo-European 2 (SIE2) conference that took place in Opava, Czech Republic. The session which followed in the series after the previous successful conference held in Copenhagen 2009 was dedicated to various aspects of Indo-European phonetics, phonemics, and morphophonemics. The papers dealt with questions relating to both the Indo-European protolanguage and specific branches of the Indo-European family. The program of the conference consisted of 40 papers, including five invited talks (Alexander Lubotsky, Gerhard Meiser, Norbert Oettinger, Georges-Jean Pinault, and Roger D. Woodard). Twenty-three papers of those presented at the conference appear in their revised version in this volume. The common denominator is historical linguistics, but some authors also extended their research into modern (mor)phonological theories. Being a selection of representative papers in Indo-European linguistics and following the tradition started in Copenhagen, the book will be valuable to all scholars interested in Indo-European linguistics.
