This book is a cross-linguistic and interdisciplinary exploration of modality within systemic functional linguistics (SFL). Drawing upon the broad SFL notion of modality that refers to the intermediate degrees between the positive and negative poles, the individual papers probe into the modality systems in English and Japanese. The papers cover issues such as the conceptual nature of modality in both languages, the characterization of modulation in Japanese, the trans-grammatical aspects of modality in relation to mood and grammatical metaphor in both languages, and the modality uses and pragmatic impairment by individuals with a developmental disorder from a neurocognitive perspective. The book demonstrates a functional account of Japanese within an SFL model of language with a fresh perspective to Japanese linguistics. It also refers to cross-linguistic issues concerning how the principles and theories of SFL serve to empirically elaborate descriptions of individual languages, which will lead to the enrichment of the theory and practice of linguistics and beyond.

This book presents a systematic corpus-based study of the semantic and morphosyntactic interaction of modality with tense, aspect, negation, and modal markers embedded in subordinate clauses. The results are critically compared with extant theories of hierarchies of grammatical categories, including those in Functional Grammar, Role and Reference Grammar, and the Cartography of Syntactic Structures.

"This thesis is a text-based study of mood, modality and evidentiality of Japanese. It describes these grammatical systems from a systemic functional perspective and explores their manifeststations in the language of news reports. The study finds that mood, modality and evidentiality are distinct systems in lexicogrammar, with mood and modality shading into each other in semantics. The study also finds that in the register of news reporting, evidentiality is not only realized interpersonally, but also realized ideationally across the ranks through projection, from clause complex, clause, group to word" -- abstract.

The emotional aspects of language have so far not received the attention they deserve. This study focuses on nonpropositional, i.e. expressive and interactional meanings of Japanese signs, with special emphasis on understanding their cognitive, psychological and social meanings. It shows how the Japanese language is richly endowed to express personal voice and emotive nuances, and confronts the theoretical issues related to this. The author proposes a new theoretical framework for Discourse Modality, a primary concern for Japanese speakers, to analyze the 'expressiveness' of language.

This book explores the nature and scope of modality in Japanese. It contains a review of the history of Japanese modality studies, as well as theoretical and empirical research and is the first collection of studies on Japanese modality written in English and offers a stimulating contrast to existing studies on Western languages.

The grammatical category of (sentence) mood has been of central interest to many branches of linguistics, including linguistic typology and systemic functional linguistics. This book is a successful integration of the typological and systemic functional approaches to mood, aiming to investigate the commonalities and variations across languages in both mood system and mood structure. To this aim, it establishes a geographically, genetically and typologically representative sample of 60 languages and provides detailed systemic functional descriptions of the mood system and mood structure of these languages. Based on such descriptions, it makes cross-linguistic comparisons of the mood system and mood structure of the languages in the sample. Structurally, it explores the cross-linguistic commonalities and variations in (i) the realizations of some major functional elements in mood structure, (ii) the realizations of mood options and (iii) the realizations of mood system. Systemically, it investigates how languages resemble and vary from each other in (i) the subtypes of major mood types, (ii) the organization of mood system and (iii) the semantic dimensions along which mood system is elaborated further in delicacy. Moreover, building on the descriptions and comparisons, it makes some generalizations about the structural and systemic features of mood and proposes some tentative explanations for the commonalities and variations languages display in mood system and mood structure. This book is an empirical and holistic approach to the typology of mood and contributes to a deeper understanding of the grammatical category. It is of special interest to systemic functional linguists, typologists, grammarians and descriptive linguists.
