This volume explores the multiple aspects of morphological complexity, offering typological, acquisitional, sociolinguistic, and diachronic perspectives. The analyses are based on rich empirical data from a wide range of languages, as well as experimental data from artificial language learning.

Brings together a wide range of approaches to morphological complexity Based on rich empirical data, including from lesser-known languages Explores both structural and sociolinguistic parameters of morphological complexity

Peter Arkadiev is Senior Researcher at the Institute of Slavic Studies of the Russian Academy of Sciences and Assistant Professor at the Russian State University for the Humanities. His research interests include language typology and areal linguistics, morphology, case and alignment systems, tense and aspect, and Baltic and Northwest Caucasian languages. He is the co-editor of Contemporary Approaches to Baltic Linguistics (with Axel Holvoet and Björn Wiemer) and Borrowed Morphology (with Francesco Gardani and Nino Amiridze), both published by De Gruyter in 2015 Francesco Gardani is Professor of Romance Linguistics at the University of Zürich.
