传统训诂学只是在汉语内部寻找解决问题的根据,这种方法对有些词语显得无能为力或是难得真相,比如从原始汉藏语沉淀下来的“化石”词语以及来自其他语言的借词,要弄清这些词语的来龙去脉,就得借助异语来求证,此即所谓异语求义法,是传统训诂学方法的现代拓展。本文阐述了异语求义法的价值,并对“鸟”的读音演变及“焚轮”、“毗岚”等词的来源进行了新的论证。 Traditions are only found in Chinese language to solve the problem. This method seems powerless or rare for some words, such as “fossil” words deposited from primitive Sino-Tibetan languages ​​and borrowed words from other languages The ins and outs of these words must be proved by the use of foreign languages. The so-called foreign language meanings are the modern expansion of the traditional methods of exegesis. This article elaborates the value of paraphrase, and makes a new argument about the evolution of the pronunciation of “bird” and the origin of such words as “burning wheel” and “adjoining lan”.
