泳游（上榮柄反尒雅曰潛行為泳郭璞注云水底行也晏子春秋曰潛行逆流百步順流七里下以周反尒雅曰順流而下曰泝游說文云從水斿聲經文作[游-方+(十/十)]俗字非正）。

泳游 (The first character is pronounced with the fanqie *y-*, [yong], from 榮 and 柄. The *Erya* states: 'Moving underwater is called diving (泳).' Guo Pu's commentary states: 'Moving along the bottom of the water.' The *Yanzi Chunqiu* states: 'Moving submerged against the current for a hundred paces, or with the current for seven li.' The second character is pronounced with the fanqie *y-*, [you], from 以 and 周. The *Erya* states: 'Going down with the current is called floating and swimming (泝游).' The *Shuowen* states: 'It takes 水 [water] as semantic and 斿 as phonetic.' Sūtra texts write it as [游-方+(十/十)], a vulgar variant, not orthodox.)
