训诂学是研究我国古代语言文字的一门传统学问。与训诂学关系密切的学科有音韵学、文字学、词汇学、语法学、文献学等,其中音韵学与训诂学之间的关系最为紧密,是训诂学经常采用的得力工具。《吕氏春秋·重言》中有这样一个著名的例子,足以说明音韵对于训诂的重要:齐桓公与管仲谋伐莒,谋未发而闻于国。桓公怪之……少顷,东郭牙至……管子曰:“子邪?言伐莒者。”对曰:“然。”管仲曰:“我不言伐莒,子何故言伐莒?”对曰:“臣闻君子善谋,小人善意。臣窃意之也。”管仲曰:“我不言伐莒,子何以意之?”对曰:“……日者臣望君之在台上也……君呿而口金,所言者莒也。”东汉高诱对其中呿、口金的字注道:“呿,开;口金,闭。…”莒“的读音现在为j u,韵母o属于闭口高元音,为什么高诱的注却说桓公发莒音时口形是张开的呢?要解释这个问题,需要借助先秦古音的知识。原来”莒“在先秦属”鱼“部字,根 Exegetics is a traditional study of the ancient Chinese language. Phonology, philology, grammar, philology and other disciplines that are closely related to Exegesis are the most closely related phonology and exegesis studies, which are often used as powerful tools in Exegesis. There is such a famous example in the Spring and Autumn Annals of Lu, which shows the importance of phonology for exegesis: Qi Huan-kong and Guan Zhong-mou’s tactics, and he did not smell of the country until it was discovered. Huanong strange ... ... a moment, the East Guo teeth to ... ...
