本論文旨在探討大南魯凱語中的借詞（loanword），並根據不同的捐贈語言（donor language）分析其語音與語義的借用模式。
在歷史發展的過程中，大南魯凱語與多種語言進行了廣泛的接觸交流並且發生了多層次的詞彙借用與音韻影響，這些語言包括了卑南語、拉阿魯哇語、卡那卡那富語、鄒語、排灣語、日語以及閩南語。
在臺灣南島語中，卑南語對大南魯凱語的影響尤為顯著，此影響體現在歷史上至少三個不同時期的詞彙借用層次。不僅如此，大南魯凱語的詞彙組成中還有來自其他臺灣南島語言的借詞，包括了拉阿魯哇語、卡那卡那富語、鄒語以及排灣語。然而這些借詞較可能是早期接觸的結果而非近期的語言互動所致，因為這些借詞也可見於其他的魯凱語方言之中。
除了來自臺灣南島語的影響，大南魯凱語還吸收了大量來自非南島語系的借詞。其中來自日語和閩南語的借詞主要涉及現代創新概念與新興事物，顯示語言接觸的時代較近。不僅如此，許多源自於日語及閩南語的詞彙是透過卑南語而進入大南魯凱語的。近年來，華語開始對大南魯凱語產生影響，惟目前仍難以進行全面的語音分析。
最後，基於借詞類型學詞表（Loanword Typology meaning list）對1,128個大南魯凱語詞彙的統計分析顯示，日語是其最主要的借詞來源，其次為卑南語與閩南語。在語義分類上，借詞比例最高的語義領域（semantic field）為：（1）現代世界（70.3%）、（2）法律（47.1%）及（3）家居（29.3%）。相較之下，受影響最小的語義領域包括：（1）功能詞（0%）、（2）情感與價值觀（0%）及（3）親屬關係（1.2%）。

This thesis investigates loanwords in Tanan Rukai, analyzing their phonological and semantic borrowing patterns by different donor languages.
Tanan Rukai has experienced extensive linguistic interaction with various languages, including Puyuma, Saaroa, Kanakanavu, Paiwan, Tsou, Japanese, and Southern Min. This has resulted in multiple layers of lexical borrowings and phonological influence.
Among the Formosan languages, Puyuma has played a significant role in influencing Tanan Rukai, contributing at least three layers of loanwords across different historical periods. Additionally, Tanan Rukai has borrowed lexical items from Saaroa, Kanakanavu, Tsou, and Paiwan, likely as a result of early contact rather than recent interactions, as these loanwords are also found in other Rukai dialects.
Beyond Formosan influences, Tanan Rukai has incorporated numerous loanwords from non-Austronesian languages. Borrowings from Japanese and Southern Min primarily involve recent innovations and modern concepts, stemming from recent interactions. In more recent times, Mandarin has begun influencing Tanan Rukai, though its impact remains too recent for a comprehensive phonological analysis.
Finally, a statistical analysis of 1,128 Tanan Rukai lexical items based on the Loanword Typology meaning list identifies Japanese as the strongest donor language, followed by Puyuma and Southern Min. The semantic fields with the highest proportion of loanwords are (1) Modern World (70.3%), (2) Law (47.1%), and (3) The House (29.3%). In contrast, the least affected semantic fields include (1) Miscellaneous Function Words (0%), (2) Emotions and Values (0%), and (3) Kinship (1.2%).
