躓頓（知利反郭注爾雅云疐頓猶倒仆也廣雅躓踏也說文從足質聲也或從叀作疐𨊢音專）。

Stumble and fall (躓頓: the fanqie of 知 and 利. Guo's commentary on the Erya states: "疐頓 means to stumble and fall prostrate." The Guangya says: "躓 means to tread." The Shuowen says: "With the radical 足 and 質 as phonetic." It is sometimes written with 叀 as 疐; 𨊢 has the sound of 專).
