Delight and joy (yǔ + shū fanqie. Zheng's commentary on the Analects says: 'Yúyú means a gentle facial expression.' The Erya says: 'Joy.' The Guangya says: 'Delight.' It takes 'heart' with yú as phonetic. In the Shuowen the character yú takes jí, zhōu, and guài; guài is gǔ + wài fanqie, jí is jīng + rù fanqie. Today vulgar usage writes it with 'moon' and 'knife', which is corrupt).
