Led by Editor in Chief Rochelle Lieber and Associate Editors Sabine Arndt-Lappe, Antonio Fàbregas, Christina Gagné, and Francesca Masini, this collection includes 115 wide-ranging and in-depth articles, encompassing all aspects of morphology, such as morphological units, inflection, derivation, compounding, and formal morphological means. Contributors at the forefront of the field discuss the major theoretical debates and methodological approaches, exploring the interface between morphology and phonology, syntax, and semantics, along with psycholinguistic, neurolinguistics, and sociolinguistic issues. The final section of the encyclopedia presents illustrative sketches of the morphological systems of a wide range of language families, from Arawak and Dravidian to Sino-Tibetan and Indo-European, offering a wide range of cross-linguistic data that will be useful to both researchers and teachers.
