《爾雅》作為中國最早的解釋詞義之書，也是最早的詞典，其收集的單字、複詞、方言、專名多達四千多詞條，成為《駢字類編》引用文獻之大宗，收錄多達一千多筆資料，引用《爾雅》既能說明詞彙語源，又能直接掌握詞義，其中有今所見的《爾雅》未盡相同，亦有已亡佚者，《駢字類編》為《爾雅》保存相當的資料，具有研究的價值。然而，引用《爾雅》時，仍存有不足之處，是使用工具書時，宜需要留意之處，俾後人能對《駢字類編》有更進一步的了解。

Erya is the first annotation book in China and the first Chinese dictionary. It collects more than 4,000 characters, words, dialects, and proper nouns and is thus a major source referenced in Pianzi leibian, which contains more than 1,000 pieces of information from Erya. Quoting Erya provides clear information of word origins and offers direct meanings. The contents cited in Pianzi leibian are not identical to those in the existing Erya, and some has even been lost. Pianzi leibian has retained a considerable amount of text of Erya and thus is of high research value. However, Pianzi leibian did not do a comprehensive job in citing Erya, and the gaps must be noted when using Pianzi leibian as a reference book. This study aimed to enhance the reader’ understanding of Pianzi leibian.
