历史文献中所遇到的札刺亦儿部是蒙古兴起以前以及在蒙古统治时期活跃于北方与西域的一支草原游牧部落。由于札剌亦儿族源的史料缺乏,而且有些历史记载相互矛盾,因此学者们的研究多趋于推理并各持己见。本文试图结合史籍记载和语言学方法,对札刺亦儿族源及其名称的词源进行探讨并提出作者新的看法。 In the historical documents, Jabal Jidou was a grassland nomadic tribe that had been active in northern and western Mongolia during the Mongolian upheaval before the rise of Mongolia. Due to the lack of historical sources and the conflicting historical records, the scholars’ research tends to reason and hold their own views. This article attempts to combine the historical records and linguistic methods to explore the etymology of the Tusi ethnic origin and its name and put forward a new view of the author.
