78.201

欲齧（下研結反說文齧噬也從齒㓞聲㓞音慳八反經從口作嚙俗字非正）。

Wishing to bite (欲齧; the second character has the fanqie 研結 [n- + -(i)è]; the Shuowen jiezi says: "齧 means to bite; it takes 'teeth' (齒) with 㓞 as phonetic; 㓞 has the fanqie 慳八 [qi- + -ā]"; in the sūtra it is written with 'mouth' (口) as 嚙, which is a vulgar character and not orthodox).
