跳躑（上亭遙反蒼頡篇云跳踴也廣雅云跳躍也下呈炙反踴身投地騰躍也跳躑二字並從足兆鄭皆聲也）。

跳躑 (Leaping and trampling: for the first character, fanqie 亭遙 [tiáo], the Cangjie pian says: '跳踴 means to leap.' The Guangya says: '跳 means to jump.' For the second character, fanqie 呈炙 [zhí], it means leaping up and throwing one's body to the ground, jumping vigorously. Both characters 跳 and 躑 are formed from 足 [foot] with 兆 and 鄭 as phonetic elements.)
