Lifespan “Changes from Above” in the Standardization of Japanese Regional Dialects: Levels of Grammar, Lexical Properties and Community Characteristics

要旨

Abstract This paper examines sociolinguistic properties of lifespan changes in language use from a non-Western perspective. Based on real-time studies in a change from above context (standardization) and panel surveys of prosody, the paper demonstrates that the stability of individuals’ language use over time varies along the following interwoven factors: (1) levels of grammar; (2) lexical properties; (3) progressive stages of a community in transition; and (4) locally constructed social identities. While segmental phonology and morphosyntax remain intact, lexical accents and vocabulary items tend to change in close linkage to sociolinguistic properties of individual words. Such changes are also motivated by the coexistence of an incoming standard, revitalized traditional dialect, and newly emerging “diaglossic” in-between variants in a community that is shifting to bidialectalism. Lifespan changes could also be community-specific, varying even within a single dialect region between two communities across which the stages of standardization and members’ locally constructed social identities differ.
