甲骨文研究自清末發掘至今，約一百多年的歷史。學者繼甲骨四堂逐字解釋到整版卜辭通讀，近年受到西方語言學影響而興起討論其語法問題。研究甲骨語法專書始於管燮初 (1914-2000)，爾後學界陸續關注此類議題，希冀瞭解甲骨文記載內容，其中闡明語法為通讀甲骨之重要關鍵。 目前針對「某芻于某」句型理解有所差異，如楊升南（1938-）、王宇信（1940~ ）、鍾柏生皆認為「于」為介詞，然魏慈德卻將「于」歸為動詞，因對「于」之詞性界定不同，造成對此句型有不同解讀方式，故本文企圖將此類句型羅列，進而釐清其 觀念。 首先，整理甲骨文「芻」之詞性，有：（一）主語。（二）謂語。（三）賓語。其中「芻」謂語，見《甲骨文合集》974 正、《甲骨文合集》2221「貞：父乙芻于王？」以上句型若將「于」作動詞會造成釋讀窒礙；但釋「芻」動詞，則屬「王芻于父乙」移位句。其次，歸納卜辭「于」後所接詞彙內容：（一）人物、對象。（二）方位、處所。（三）時間詞。（四）代詞。以上四類「于」皆屬「介詞」。最後，分析「某芻于某」之句型，得出此屬「主語＋動詞（芻）＋介賓詞組（于某）」形式，而用法應從楊升南、鍾柏生解釋為「（殷王命令）某人到某地主管芻牧之事」較可信。

Oracle-bone inscriptions have been carefully investigated for over one hundred year since the late Qing Dynasty (1644-1912). In recent years, Western linguistists have joined the rank of studies in oracle-bone inscriptions, and so syntactical problems have come into being. Many scholars have enquired into either word-to-word phrasing or full-page inscription reading. The study of syntactic issues began with Guan Xie-chu (1944-2000), followed by numerous scholars devoted to various aspects of the linguistic issue surrounding the oracle bones. They hope to understand the true meaning latent in the oracle-bone inscriptions. To clarify the syntactical difficulties is essential to the understanding of oracle-bone inscriptions. This article has attempted to syntactically analyze a controversial set-phrase, mou-chu-yü-mou (a certain person assigned somewhere to attend to the pasturing business). So far, the interpretation of this term has still incited divergences. For example, scholars like Yang Sheng-nan (1938-), Wang Yu-xin (1940-), and Zhong Bo-sheng have held that the character yü 于 should be regarded as a preposition. However, Others like Wei Ci-de considered that the yü 于 should be a verb. Owing to the differences in reading of the syntax for this character, a variety of explanations and interpretations have thus emerged. From my point of view, first of all, the syntax of the character chu 芻 includes a subject, predication and object respectively. If the chu 芻 should be regarded as a predication, such as the set-phrase, “貞：父乙芻于王？” (cited from “Jia-gu-wen he-ji No. 974 topside” and “Jia-gu-wen he-ji No. 2221”), and if the subsequent character yü 于 should be treated as a verb, then the set-phrase mou-chu-yü-mou 某芻于某 would be just too hard to read and understand. However, should the character chu 芻 be regarded as a verb, this set-phrase could be understandably transposed into “王芻于父 乙”. Secondly, if the character yü 于 includes four functions--(1) figure and target, (2) position and place, (3) temporal expression, (4) pronouns, the yü 于 should be placed as a proposition. Finally, analyzing the sentence structure of the set-phrase “某芻于某”, I found out that its sentence structure should be like “subject + verb + preposition or object,” and the usage should be correctly explained by Yang Sheng-nan and Zhong Bo-sheng as parallel to that expression, “殷王命令 (the order from King Yin)”, which means that someone goes to somewhere for managing a pastureland.
