楚系簡帛「」字的釋讀，迄今已有十幾種不同意見。本文逐一檢視各家說法之後，確認此字應隸定作「」，在《緇衣》和《語叢四》簡文中可讀作「轍」，在《凡物流形》簡文中可讀作「徹」。在研究過程中，對於上博竹書《周易》簡32「□」字、馬王堆帛書《陰陽五行（甲篇）》149行「□」字、郭店楚簡《老子（甲）》簡27「」字、《汗簡》「撤」字條「」字、《古文四聲韻》「轍」字條「」和「」字，四版《金文編》附錄下204號「□□」等字，以及附錄下205號「」字，筆者也分別提出個人見解。此外，還對殷商甲骨文「□□□□」等字是否為「曷」字，以及西周金文「」字、春秋金文「」字是否為從「曷」旁的字提出質疑。

There has been considerable disagreement among scholars on the interpretation of the character “□” found in bamboo silk scripts of the Chu 楚 region. Against this background, this paper explores this character from different perspectives, finally coming to the conclusion that it should be interpreted as “□” and that it should be read as zh□ in Ziyi 緇衣 and Yucong（IV）語叢四. This study makes some detailed supplementary statements about the process of figuration and transformation of the character h □ 曷, and also proposes new interpretations of the following characters: “□” in the Shanghai Chu slips, “” in the Mawangdui boshu 帛書, “” in the Guodian Chu slips, “□” in the Hanjian 汗簡, and “,” in the Guwen sishengyun 古文四聲韻. Besides this, some characters in oracle-bone inscriptions traditionally suspected to be forms of h 曷, such as “□□□□” or characters found in bronze inscriptions in which h□ 曷 is an element, such as “□, □” , are also thoroughly investigated.
