This volume contains a selection of thoroughly revised contributions to the 9th European Conference on Formal Description of Slavic Languages. The authors apply recent formal models in linguistics to issues concerning the lexicon, morphology, syntax, semantics, information structure, and phonology in Bosnian/Croatian/Serbian, Bulgarian, Czech, Polish, Russian, and Slovenian. Topics of the papers include aspect and tense, axial expressions, case, control, copula, ditransitives, focus particles, indefiniteness, infinitives, nominal phrases, numerals, temporal adverbials, trochaic lengthening, and verb stems. The papers aim at proposing both descriptively accurate and explanatorily adequate analyses, considering all linguistic levels and interfaces. Due to its analytical scope and the broad spectrum of languages covered, the volume reflects the state of the art in current formal Slavic linguistics.
