無易（盈益反賈注國語云變易也異也孔注尚書云改也字書移也廣雅轉也古文作易象形如蜥蜴蟲形也說文賈秘書說日月為易字一云從勿省此皆情斷非正也）。

No change (無易: the second is pronounced with the fanqie 盈益 [yì]. Jia's commentary on the Guoyu says: "To change and transform; different." Kong's commentary on the Book of Documents says: "To alter." Character dictionaries say: "To move." The Guangya says: "To turn." In ancient script it is written as 易, picturing a chameleon-like lizard. The Shuowen notes that Secretarial Assistant Jia explained the character 易 as consisting of the sun and the moon, while another theory says it derives from an abbreviated 勿; these are all speculative conclusions and not correct).
