躓頓（古文䠟躓二形今作疐同陟利反謂挫辱之也左傳云躓而蹎案躓猶頓也廣雅云躓蹋也）。

Stumble and fall (躓頓: the ancient script has the two forms 䠟 and 躓; now written 疐, the same, with the fanqie 陟利 [zhì], meaning to be thwarted and humiliated; the Zuozhuan says: "He stumbled and fell"; considering this, 躓 is like 頓 [to stumble]; the Guangya says: "躓 means to tread on").
