民謠在傳統研究上有兩個缺點：一、素材僅限於少數韻行；二、
只著重語言個別派生規律，而缺乏普遍性。本文建立一個720 行的彰
化閩南語民謠語料庫，並提出一個非派生分析。從這個語料庫顯示，
大部分的韻行屬陽性節律，占90.67%，而拍板分享則是避免陰性節律
的手段。本文在Prince and Smolensky (1993)的優選理論框架下，提出
一組節律制約。這些制約屬於普遍語法的一部分，而在彰化民謠中呈
現語言個別性的層級排序。

Traditional treatments of folk verse have two disadvantages. First, they focus
only on a small number of lines. Second, they pursue derivational rules on a
language-specific basis, but lack universal validity. This paper establishes a corpus of
720 lines of Southern Min folk verse in Changhua and provides a non-derivational
analysis of the data. The corpus shows a preference for masculine rhythm, which is
found in 90.67% of the data. Metrical beat sharing, then, allows feminine lines to be
avoided. This paper puts forth a set of metrical constraints under the framework of
Prince and Smolensky’s (1993) Optimality Theory. The constraints are part of
Universal Grammar, but are ranked language-specifically in Changhua folk verse.
