This edited book brings together studies on morphological case in English, Japanese and Bantu languages from morphosyntactic, semantic and historical perspectives. Languages are divided into two types in terms of case: nominative-accusative languages and ergative-absolutive languages. Even if we limit our attention to nominative-accusative languages, morphological case on subjects and objects vary across languages or even within a single language, either synchronically or diachronically. For instance, certain stative predicates in Japanese allow their subjects and objects to be marked with dative and nominative case, and subjects in adnominal phrases in Japanese can be marked with genitive case; moreover, the possibility of marking subject in adnominal clauses has been sharply decreasing in the last hundreds of years. In fact, what predicates can license what case can have certain degrees of idiolectal, dialectal, and/or geographical micro-variations and intergenerational and/or diachronic micro-change. This book draws parallels and examines differences between examples of European, Asian and African languages, and it will be of interest to researchers in Theoretical Linguistics, particularly those involved with Language Variation and Change, Morphology and Syntax, and Generative Grammar.
