Dieya 疊雅 "Correct reduplications" or "The [Er]ya on reduplications" is a glossary written during the late Qing period 清 (1644-1911) by Shi Menglan 史夢蘭 (1818-1898), courtesy name Xiangya 香崖, 湘崖 or Xiuya 秀崖, style Yannong 硯農. Shi is known as the compiler of several local gazetteers (Leting xian zhi 樂亭縣志, Yongping fu zhi 永平府志), author of several poetry collections and poetry critique (Jinshi gongci 金史宮詞, Yongping shicun 永平詩存, Zhiyuan shihua 止園詩話, Er'er shuwu shicao 爾爾書屋詩草, Quanshi gongci 全史宮詞), and some linguistic studies like the Dieya and the books Yanshuo 燕說, Gujin yan shishi 古今諺拾遺, and Yudi yubian 輿地韻編.
In bibliographies, the Dieya belongs to the category of books of "lesser learning" (Xiaoxue 小學), often translated as "lexicography". According to the preface, the 13-juan long book was finished in 1864.
Shi Menglan collected all kinds of reduplicative words (diezi 疊字) mentioned in a vast amount of traditional books, from the Confucian Classics and the various "masters and philosophers", and to historiographic works. The words in his dictionary are arranged according to the chapter titles used in the glossary Erya 爾雅.
Although some of the words Shi Menglan included in his dictionary are already mentioned in older glossaries, he also added many new ones. Shi Menglan deserves credit for his detailed comments to the lexemes of his book and the diligent philological and text-critical work he had done.
At the end of his book, a chapter on double-character personal names is added (Shuangminglu 雙名錄).
