不論在台灣或日本，日語教育或日本語學的領域，都正邁入個大轉變時期。其背後都存在著日本語學的重要課題。回顧目前使用於日語教育之上的日語相關文法概念的發展，大體可以區分為三大類。一為沿用自日本語學史上由索緒爾（Saussure）的共時言語側面而進行分析的橋本文法等國語文法之依據文法的品詞分類而成的分類體。其二為用之於日本語學之上，導入歐美言語研究的觀點之種種概念。其三為應日本語教育之需而產生的「複合詞」、「基本文型」等日本語教育上常用的文法概念。如此不同立場的產生諸多不同見解立場的混淆現象，影響到日本語研究以及應用於日語教育教育上的說法不一致，而產生種種的困難。比現象在台灣的日語界，已是時常耳聞、廣為周知的事實。本論文首先回顧近年來逐漸活絡有關文法概念或重新審視品詞的論點，再指出問題所在。並提供從具體的文本分析的表達主體的表達活動之個人言語的視點，重新省思目前共時言語為中心的文法概念的一個契機

Japanese-language education and Japanese study have entered a big transition stage now. The problem of Japanese study exists in this background. The flow of a grammatical concept concerning Japanese used by Japanese-language education has two currents. One is the taxonomy from a Saussure Lang side to the extension of a national language historical aspect and it means some classifications of a grammatical part of speech that has the origin of the Japanese historical grammar like Hashimoto grammar etc. In addition, there are various concepts used in the Japanese study that has introduced the viewpoint of the origin of the research about language in Europe and America following it. Another trends are many grammatical concepts in Japanese-language educations such as ＂Compound word＂ and ＂Basic sentence pattern＂ that were born from the necessity of Japanese-language teaching. The mixture phenomenon in such many different standpoints have caused confusion and difficulty of contents on the explanation that used in Japanese researches and teachings. It introduces the outline of the activated discussion related to the review of grammatical concept and part of speech in this thesis. And, this thesis will review some grammatical concepts by the Lang from a parole aspect of the expression activity on expression subject that suits concrete texts as a problem institution
