纳西东巴文的“若喀”字类,有的学者识别为以独立的文字系统;有的学者则认为是纳西族的方言文字中的一种,莫衷一是,需要作细致的专题研究。本文对李霖灿、张琨、和才的《么些象形文字字典》第十三部分即“若喀”字类的所有字符的字源作了全面考释。尤其对其中标识为“字源不识”的部分提出了新的解释。 Some scholars have identified as an independent writing system in Naxi Dongba writing. Some scholars regard it as one of the dialects of the Naxi people. There is a lack of agreement on this subject and the need for detailed and special studies. This article makes a comprehensive examination of the etymological sources of all the characters of Li Quncan, Zhang Kun, and Talented “Some Pictograph Dictionary”, the thirteenth part of which is the character of “Ruka”. In particular, a new explanation has been put forward for the part in which the source is not known.
