再論天津方言三字組變調

Trisyllabic Tone Sandhi in Tianjin Revisited

自從一九八零年代中期，植基於衍生學派或優選理論有關天津方言三字組變調的分析陸續發表，其中爭辯的關鍵在於HL.L.L的單字調組合如何具現成HL.LH.L。本文利用組內一致性的概念，一方面反映心理學的相似性分類，一方面呼應優選理論的最佳變化模式，從一全新的角度詮釋天津方言三字組變調。

This paper reanalyzes trisyllabic tone sandhi in the Tianjin dialect, which has invoked a generative line of research since mid 1980s. Among the 64 (43) trisyllabic tonal strings, how HL.L.L surfaces as HL.LH. L has been the crux of heated debate among the derivational and Optimality-Theoretic approaches. This paper appeals to the notion of set consistency, the spirit of which reflects similarity-to-category in psychology and Optimal Paradigms in Optimality Theory, to account for Tianjin trisyllabic tone sandhi from a brand new perspective.
