在現代詩人中，鄭愁予的名號是響亮的，擁有廣大的讀者，詩評家讚美他的詩作「聲籟華美」，然而聲籟如何華美卻無法說出所以然來，藉由語言風格手法的分析方式，筆者試圖進入詩人的堂奧，一窺詩人創作的秘密，剖析鄭愁予在音律使用的獨特性。本論試圖歸納出詩人在聲母、韻母、同字、聲調上手法的匠心獨具，使用的特殊手法，形成創作上的個人風格，造成誦讀上的美感。

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。 四音節部分重疊詞是由並列複合詞和重疊詞這兩組詞素組成。在深層結構中，這兩組詞素分屬兩層。透過居問的基架層，這兩組詞素穿插交織成複雜式並列複合詞。McCarthy (1981)所提出的詞素分層假說，正可以用來呈現這種構詞方式。 雙音節形容詞有兩種重疊類型:ABAB和AABB。論文中指出AABB的派生方式是把ABAB中間兩個音節的位置對調。這種重疊構詞過程，將以基模構詞模式及最佳選擇理論清楚呈現。 象聲詞的擬聲部分，是山一組重疊的聲母和兩個韻母這兩組詞素所構成。這兩組詞素是以聲韻基模為中介所交織而成。以這種方式派生出來的雙音節象聲詞，可以再經由和雙音節形容詞相同的方式，重疊為AABB的形式。論文中以詞素分層假說和基模構詞模式呈現這類構詞過程。此外，雙音節形容詞和象聲詞重疊形式中的一個音節或聲母，可能會由另一個音節或聲母取代，來派生新詞。論文申以McCarthy和Prince (1990)所提出的「音律替換」呈現這種取代的過程。 / 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. Quadrisyllable partial reduplicated words consist of two parts: one is coordinate compound and the other reduplicated word. These two parts exist in different tiers in the deep structure. They interweave to form a complicated compound through a skeletal tier in between. The morpheme tier hypothesis proposed by McCarthy (1981) is employed to show how this type of words are formed. Disyllabic adjectives have two different categories of reduplication: ABAB and AABB. The writer argues that AABB is derived from ABAB by metathesis of the two syllables in the middle. The process of this reduplication can be explicitly shown in terms of template morphology and optimality theory. The core of onomatopoetic words is constructed from two sets of morphemes: a reduplicated onset morpheme and a morpheme with two rimes. These two are put together through an intermediate onset and rime tier (OR template). The disyllabic onomatopoetic words derived in this way can undergo reduplication in the same way as the second type of disyllabic adjectives, i.e. AABB. The writer adopts morpheme tier hypothesis and template morphology to represent these morphological processes. Moreover, another syllable or onset may replace a syllable or an onset of a reduplicated form of disyllabic adjectives or onomatopoetic words. The replacement process is represented by 'Melodic Overwriting* proposed by McCarthy and Prince (1990).
