本論文依McCarthy和Prince (1990, 1993)所提出的韻律構詞理論，探討四種台閩語重疊詞（即：動詞、四音節部分重疊詞、雙音節形容詞及象聲詞）。對僅適用於述補及並列複合動詞的重疊構詞方式，做了深入分析。分析顯示，抑揚格音步複合動詞，會複製帶有重音的最後一個音節做為重疊詞素，附加於詞尾；而揚抑格音步複合動詞，則會複製帶有重音的第一個音節做為重疊詞素，附加於詞頭。以最佳選擇理論可以清楚說明以上所論證的重疊構詞方式。 This thesis explores four kinds of reduplicated words in Taiwan Min (i.e. verbs, quadrisyllablic partial reduplicated words, disyllabic adjectives and onomatopoetic words) within the framework ofprosodic morphology proposed by McCarthy and Prince (1990, 1993). The reduplication process used only in resultative and coordinate compound verbs is thoroughly investigated. This investigation shows that an iambic foot compound verb will copy its stressed final syllable as a reduplicant and a suffix, while a trochaic foot word will copy its stressed first syllable as a reduplicant and a prefix. This argumentative reduplication can be clearly accounted for by optimality theory.
