Despite decades of research on the reconstruction of proto-Korean-Japanese (pKJ), some scholars still reject a genetic relationship. This study addresses their doubts in a new way, interpreting comparative linguistic data within a context of material and cultural evidence, much of which has come to light only in recent years. The weaknesses of the reconstruction, according to J. Marshall Unger, are due to the early date at which pKJ split apart and to lexical material that the pre-Korean and pre-Japanese branches later borrowed from different languages to their north and south, respectively. Unger shows that certain Old Japanese words must have been borrowed from Korean from the fourth century C.E., only a few centuries after the completion of the Yayoi migrations, which brought wet-field rice cultivation to Kyushu from southern Korea. That leaves too short an interval for the growth of two distinct languages by the time they resumed active contact. Hence, concludes Unger, the original separation occurred on the peninsula much earlier, prior to reliance on paddy rice and the rise of metallurgy. Non-Korean elements in ancient peninsular place names were vestiges of pre-Yayoi Japanese language, according to Unger, who questions the assumption that Korean developed exclusively from the language of Silla. He argues instead that the rulers of Koguryo, Paekche, and Silla all spoke varieties of Old Korean, which became the common language of the peninsula as their kingdoms overwhelmed its older culture and vied for dominance. Was the separation so early as to vitiate the hypothesis of a common source language? Unger responds that, while assuming non-relationship obviates difficulties of pKJ reconstruction, it fares worse than the genetic hypothesis in relation to non-linguistic findings, and fails to explain a significant number of grammatical as well as lexical similarities. Though improving the reconstruction of pKJ will be challenging, he argues, the theory of genetic relationship is still the better working hypothesis. The Role of Contact in the Origins of the Japanese and Korean Languages shows how an interdisciplinary approach can shed light on a difficult case in which the separation of two languages lies close to the time horizon of the comparative method.

The Studies in Japanese and Korean Historical and Theoretical Linguistics and Beyond presented in honour of Prof. John B. Whitman includes contributions by a range of mid-generation to senior scholars among his closest colleagues and collaborators representing the front line of contemporary research in the areas of historical and theoretical linguistics of Japanese and Korean as well of Chinese, Turkish, and Russian. Particularly, in all these areas it deals with still ongoing debates about the important issues in historical and theoretical linguistics concerning these languages that are reflected in articles often representing opposing points of view. This book can serve as a good introduction to the current state-of-art and the most essential problems in the fields it covers.

A History of the Korean Language is the first book on the subject ever published in English. It traces the origin, formation, and various historical stages through which the language has passed, from Old Korean through to the present day. Each chapter begins with an account of the historical and cultural background. A comprehensive list of the literature of each period is then provided and the textual record described, along with the script or scripts used to write it. Finally, each stage of the language is analyzed, offering new details supplementing what is known about its phonology, morphology, syntax, and lexicon. The extraordinary alphabetic materials of the 15th and 16th centuries are given special attention, and are used to shed light on earlier, pre-alphabetic periods.

This book presents a comprehensive and critical overview of historical phonology as it stands today. Scholars from around the world consider and advance research in every aspect of the field. In doing so they demonstrate the continuing vitality and some continuing themes of one of the oldest sub-disciplines of linguistics. The book is divided into six parts. The first considers key current research questions, the early history of the field, and the structuralist context for work on segmental change. The second examines evidence and methods, including phonological reconstruction, typology, and computational and quantitative approaches. Part III looks at types of phonological change, including stress, tone, and morphophonological change. Part IV explores a series of controversial aspects within the field, including the effects of first language acquisition, the status of lexical diffusion and exceptionless change, and the role of individuals in innovation. Part V considers theoretical perspectives on phonological change, including those of evolutionary phonology and generative historical phonology. The final part examines sociolinguistic and exogenous factors in phonological change, including the study of change in real time, the role of second language acquisition, and loanword adaptation. The authors, who represent leading proponents of every theoretical perspective, consider phonological change over a wide range of the world's language families. The handbook is, in sum, a valuable resource for phonologists and historical linguists and a stimulating guide for their students.

The UNESCO atlas on endangered languages recognizes the Ryukyuan languages as constituting languages in their own right. This represents a dramatic shift in the ontology of Japan’s linguistic make-up. Ryukyuan linguistics needs to be established as an independent field of study with its own research agenda and objects. This handbook delineates that the UNESCO classification is now well established and adequate. Linguists working on the Ryukyuan languages are well advised to refute the ontological status of the Ryukyuan languages as dialects. The Ryukyuan languages constitute a branch of the Japonic language family, which consists of five unroofed Abstand (language by distance) languages.The Handbook of Ryukyuan Languages provides for the most appropriate and up-to-date answers pertaining to Ryukyuan language structures and use, and the ways in which these languages relate to Ryukyuan society and history. It comprises 33 chapters, written by the leading experts of Ryukyuan languages. Each chapter delineates the boundaries and the research history of the field it addresses, comprises the most important and representative information.

This book deals with shared verb morphology in Japanese and other languages that have been identified as Transeurasian (traditionally: “Altaic”) in previous research. It analyzes shared etymologies and reconstructed grammaticalizations with the goal to provide evidence for the genealogical relatedness of these languages.

In the more than 3,000 years since its invention, the Chinese script has been adapted many times to write languages other than Chinese, including Korean, Vietnamese, Japanese, and Zhuang. In Sinography: The Borrowing and Adaptation of the Chinese Script, Zev Handel provides a comprehensive analysis of how the structural features of these languages constrained and motivated methods of script adaptation. This comparative study reveals the universal principles at work in the borrowing of logographic scripts. By analyzing and explaining these principles, Handel advances our understanding of how early writing systems have functioned and spread, providing a new framework that can be applied to the history of scripts beyond East Asia, such as Sumerian and Akkadian cuneiform.
