駛流（上所吏反蒼頡篇云駛速疾也從馬史聲也經文作駛音古穴反駃騠馬名非駛疾義下流字說文從水從㐬音他忽反倒㜽也㜽音子經文作流非也古文又作㳅騠音柱奚反良馬也生走乃母）。

Swift current (駛流: for the upper, suǒ + lì [shǐ]; the Cangjie pian says, "駛 means swift and rapid; derived from 馬 with 史 as phonetic." The sūtra text writes it as 駛, pronounced gǔ + xué [jué], the name of the juétí horse, which does not convey the meaning of swiftness. For the lower character 流, the Shuowen derives it from 水 and 㐬, pronounced tā + hū [tū], meaning an inverted child (㜽); 㜽 is pronounced zǐ. The sūtra writing it as 流 is incorrect. In ancient script it is also written as 㳅. 騠 is pronounced zhù + xī [tí], an excellent horse; as soon as it is born it runs alongside its mother).
