長汀客語的連調變化：分析上的挑戰

Changting Hakka Tone Sandhi: Analytical Challenges

長汀客語有非常複雜的連調變化，使得任何分析方法都為之卻步，無論是以基於規律的生成模型或是優選理論。本文以最大的可能及合理的步驟進行檢視，發現目前上述兩種理論在描述上都有所不足。客語是嚴厲考驗我們概念工具是否妥適的僅見的例子。

The Hakka dialect of Changting exhibits extraordinarily complex tone sandhi patterns, that present daunting analytical challenges to any theory, including rulebased generative model as well as Optimality Theory. This paper examines the possible extensions and logical moves within both theories, and concludes that both theoretical models in their current form fall short of their descriptive goals. Hakka is a limiting case that severely tests the adequacy of conceptual tools at our disposal.
