This volume surveys the current debate on the morphome, bringing together experts from different linguistic fields--morphology, phonology, semantics, typology, historical linguistics--and from different theoretical backgrounds, including both proponents and critics of autonomous morphology. The concept of the morphome is one of the most influential but contentious ideas in contemporary morphology. The term is typically used to denote a pattern of exponence lacking phonological, syntactic, or semantic motivation, and putative examples of morphomicity are frequently put forward as evidence for the existence of a purely morphological level of linguistic representation. Central to the volume is the need to attain a deeper understanding of morphomic patterns, developing stringent diagnostics of their existence, exploring the formal grammatical devices required to characterize them adequately, and assessing their implications for language acquisition and change. The extensive empirical evidence is drawn from a wide range of languages, including Archi, German, Kayardild, Latin and its descendants, Russian, Sanskrit, Selkup, Ulwa, and American Sign Language. As the first book to examine morphomic patterns from such a diverse range of perspectives and on such a broad cross-linguistic basis, The Morphome Debate will be of interest to researchers of all theoretical persuasions in morphology and related linguistic disciplines.

This is the first typologically-oriented book-length treatment of morphomes, systematic morphological identities, usually within inflectional paradigms, that do not map onto syntactic or semantic natural classes. In the first half of the book, Borja Herce outlines the theoretical and empirical challenges associated with the identification and definition of morphomes, and surveys their links with related notions such as syncretism, homophony, segmentation, and economy, among others. He also presents the different ways in which morphomic structures in a language have been observed to emerge, change, and disappear. The second part of the book contains its core contribution: a database of 120 morphomes across 79 languages from a range of families, which are presented and analysed in detail. A range of findings emerge as a result, including the idiosyncratic nature of morphomes in the Romance languages, the existence of cross-linguistically recurrent unnatural patterns, and the preference for more natural structures even among morphomes. The database also allows further explorations of other issues such as the effect of learnability and communicative efficiency on morphological structures, and the lexical and grammatical informativity of morphs and their distribution.

Morphological variation is a rather young, yet fascinating topic to study in its own right because it offers challenging evidence both for the autonomy of morphology (morphomic processes) as well as for its tight interconnection with other grammatical domains, notably phonology and syntax. Covering a wide range of phenomena (e.g. negation structures, form function-mismatches in the verbal and nominal domain, loss of morphosyntactic feature values, etc.), the contributions to this volume combine in-depth empirical studies with the explanatory potential of modern theories of grammar as well as approaches for capturing and modelling microtypological diversity.

Recent years have seen a growing interest in linguistic phenomena whose formal manifestation and underlying licensing conditions represent the convergence of two or more areas of the grammar, an area of investigation particularly invigorated in recent generative research by developments such as phase theory (cf. Chomsky 2001; 2008) and the cartographic enterprise (cf. Rizzi 1997; Cinque 1999). In this respect, the dialects of Italy are no exception, in that they present comparative Romance linguists and theoretical linguists alike with many valuable opportunities to study the linguistic interfaces, as highlighted by the many case studies presented in this volume which provide a series of original insights into how different components of the linguistic system – syntactic, phonetic, phonological, morphological, semantic and pragmatic – do not necessarily operate in isolation but, rather, interact to license phenomena whose nature and distribution can only be fully understood in terms of the formal mapping between the interfaces.

This book provides a view of where the field of morphology has been and where it is today within a particular theoretical framework, gathering up new and representative work in morphology by both eminent and emerging scholars, and touching on a very wide range of topics, approaches, and theoretical points of view. These seemingly disparate articles have a common touchstone in their focus on a word-based, paradigmatic approach to morphology. The chapters in this book elaborate on these basic themes, from the further exploration of paradigms, to studies involving words, stems, and affixes, to examinations of competition, inheritance, and defaults, to investigations of morphomes, to ways that morphology interacts with other parts of the language from phonology to sociolinguistics and applied linguistics. The editors and contributors dedicate this volume to Prof. Mark Aronoff for his profound influence on the field.

The collected articles in this volume address an array of cutting-edge issues in the field of historical linguistics, including new theoretical approaches and innovative methodologies for studying language through a diachronic lens. The articles focus on the following themes: I. Case & Argument Structure, II. Alignment & Diathesis, III. Patterns, Paradigms, & Restructuring, IV. Grammaticalization & Construction Grammar, V. Corpus Linguistics & Morphosyntax, VI. Languages in Contact. Papers reflect a wide range of perspectives, and focus on issues and data from an array of languages and language families, from new analyses of case and argument structure in Ancient Greek to phonological evidence for language contact in Vietnamese, from patterns of convergence in Neo-Aramaic to the development of the ergative in Basque. The volume contributes substantially to the debate surrounding core issues of language change: the role of the individual speaker, the nature of paths of grammaticalization, the role of contact, the interface of diachrony and synchrony, and many other issues. It should be useful to any reader hoping to gain insight into the nature of language change.

The volume discusses the breadth of applications for an extended notion of paradigm. Paradigms in this sense are not only tools of morphological description but constitute the inherent structure of grammar. Grammatical paradigms are structural sets forming holistic, semiotic structures with an informational value of their own. We argue that as such, paradigms are a part of speaker knowledge and provide necessary structuring for grammaticalization processes. The papers discuss theoretical as well as conceptual questions and explore different domains of grammatical phenomena, ranging from grammaticalization, morphology, and cognitive semantics to modality, aiming to illustrate what the concept of grammatical paradigms can and cannot (yet) explain.
