日語表示否定概念的漢語前綴詞素有「不-」「無-」「非-」「未-」 等，先行研究針此四個類義詞素的相関研究，大都以這些否定漢語前綴詞素輿漢語。和語詞根所結合的派生詞 (例如「不手際」「無神経」「非公開」「未完成」等)為分析之封象。黙而，近來日語外來語在日語裡不僅僅只是車純的借用タ卜來語，進而在日語的構詞裡不断替揮其遁詞功能，例如「非ミステリー」「無ダイヤ」「未チャレンジ」等否 定漢語前綴詞素輿外來語詞根所結合之語例也不少。 本論文即以此四個否定漢語前綴詞素輿タ卜來語詞根結合之派生詞為研究考察之封象，従否定漢語前綴詞素所結合之タ卜來語詞根的品詞性、否定内容的範圏、以及前綴詞素的否定意義功能之三個觀點來探討。並和博統的[不．無．非．禾+漢語．和語詞根]派生詞相封比，分析二者究寛有何相似及相異之慮，以閣明[不．無．非．未+外來語調根]派生詞的構詞特徴。最後，並論述在肯定否定的封立概念量尺上， [不．無．非．未+外來語詞根]派生詞與博統的[不．無．非．未+漢語．和語詞根]派生詞之間本質的差異性。

“FU-”, “MU-”, “HI-”, “MI-” are all Japanese Kango Prefixes showing negative meanings. Prior researches on the for prefixes mostly focus on their Kango and Wago derivatives. For examples, “FUTEGIWA”, “MUSHINKEI”, “HIKOUKAI”, “MIKANSEI”..etc. However, we found that in recent years, Gairaigo are not only borrowed words from foreign languages, but also have word-forming abilities to create new vocabularies. Such as “HIMISUTERII”, “MUDAIYA”, “MICHARANGI” are all derivatives with combinations of negative Kango prefixes and Gairaigo roots. The purpose of this article is to analyze the derivatives with combinations of the four negative Kango prefixes and Gairaigo roots. The analysis was made from three prospects: The word classes of the Gairaigo roots, ranges where the negative prefixes cover, functions of the negative prefixes. Furthermore, we took those derivatives to compare with the traditional derivatives with the combinations of “FU-”, ”MU-”, ”HI-”, ”MI-”+Kango or Wago roots, in order to find out the similarities and differences between the two sets of derivatives. Through the comparison processes, we were able to summarize the word-forming features of the “FU-”, ”MU-”, ”HI-”, ”MI-”+ Gairaigo　roots. At the end, we also indicated the essential differences between the derivatives of the “FU-”, ”MU-”, ”HI-”, ”MI-”+ Gairaigo roots and the traditional “FU-”, ”MU-”, ”HI-”, ”MI-”+Kango or Wago roots on the base of positive-negative spectrums.
