Aim The aim of Morphology is to publish high quality articles that contribute to the further articulation of morphological theory and linguistic theory in general, or present new and unexplored data. Relevant empirical evidence for the theoretical claims in the articles will be provided by in-depth analyses of specific languages or by comparative, cross-linguistic analyses of the relevant facts. The sources of data can be grammatical descriptions, corpora of data concerning language use and other naturalistic data, and experiments. Scope Morphology publishes articles on morphology proper, as well as articles on the interaction of morphology with phonology, syntax, and semantics, the acquisition and processing of morphological information, the nature of the mental lexicon, and morphological variation and change. Its main focus is on formal models of morphological knowledge, morphological typology (the range and limits of variation in natural languages), the position of morphology in the architecture of the human language faculty, and the evolution and change of language. In addition, the journal deals with the acquisition of morphological knowledge and its role in language processing. Articles on computational morphology and neurolinguistic approaches to morphology are also welcome. The first volume of Morphology appeared as Volume 16 (2006). Previous volumes were published under the title Yearbook of Morphology.
