Outline of Final Research Achievements

I conducted seven joint research projects with different linguistic laboratories both within and outside Japan. In addition to contributing to the purely academic advancement, I aimed to establish a robust international research network for the areas of morphology and word-formation. Five of the projects focused on word-level phenomena that are widely attested in the world’s languages. These included lexical/grammatical borrowing, adjectival derivation, coordinate compounding, multiple exponence, and onomatopoeias. In the remaining two projects, my collaborators and I investigated the theoretical foundations of these phenomena and succeeded in theorizing "competition" in word-formation. The results demonstrate that the clear distinction between I-language and E-language (Chomsky 1986) is an invaluable methodological tool for extracting reliable data from available linguistic resources to reveal hitherto hidden aspects of morphological competence.

Academic Significance and Societal Importance of the Research Achievements

言語には音、語、文という基本単位があるが、音や文に比べ、語という単位の自律性は理論的には疑われることが多かった。本研究成果の学術的意義は、語も音や文と同様に自律的な単位であり、別の単位に還元することはできないことを示した点にある。レキシコンにはそれ固有の理論があることは今や明らかである。本課題のプロジェクトで研究したどの言語現象においても、話者は個々の語彙素についてまとまりをなす知識を有していること、そしてその情報を土台にして派生や複合の操作を使って新たな語彙素を作りだすことが確かめられた。海外で積極的に成果発表を行い、日本語やその方言についての理解を深めてもらうようにした。
