變易 (Change and transformation: [變 has the] fanqie 兵汴 [biàn]. Jia's commentary on the Guoyu says: 'To alter.' The Cheng weishi lun says: 'The alteration of form and substance over time is called 變.' The Shuowen jiezi agrees with the Guoyu, deriving it from 攴 with the sound 䜌. The lower character has the sound 亦 [yì]. Kong's commentary on the Shangshu says: 'To alter and exchange.' Jia's commentary on the Guoyu says: 'To alter; to differ.' The Shuowen jiezi says: 'A chameleon; when in a house it is called a gecko, and when in marshes it is called a chameleon; a pictographic character.' Another view says: 'Sun and moon make 易, a character of nine strokes in all, which is an associative compound').
