《尔雅》中所收录的虚词反映出先秦时期人们对虚词重要性的认识,从先秦大量文献中可以印证,但也可从文献中发现其中一些虚词的用法并未收录。 The function words included in “Erya” reflect the people’s understanding of the importance of function words during the Pre-Qin period, which can be confirmed from a large number of documents in pre-Qin period. However, some of the usage of function words found in the literature are not included.
