Three-Kingdoms Wèi philologist, zì Zhìràng 稚讓, of Qīnghé 清河 (modern southern Hebei). Active under Wèi Míngdì in the Tàihé era (227–232), holding the rank of Imperial Academician (博士). His name is sometimes written 楫 with the wood radical, but the parallel of his zì “Zhìràng” (the ràng of yīràng 揖讓 “to bow and yield”) confirms 揖 as correct. He authored three lexicographic works: Pícāng 埤倉, Gǔjīn zìgǔ 古今字詁, and Guǎngyǎ 廣雅 KR1j0008. Only the Guǎngyǎ survives, having been preserved through the Suí imperial scholar Cáo Xiàn’s 曹憲 phonetic-gloss recension; the other two are known only from quotation in Northern-Wèi Jiāng Shì’s 江式 Memorial on the Script and elsewhere. With Xǔ Shèn 許愼 (Eastern Hàn) and Lù Démíng 陸德明 (Suí–Táng), Zhāng Yī is one of the cornerstone figures of the pre-Táng xiǎoxué tradition.
