慣習（卦患反前第四百三十八卷已釋爾雅慣習也言久習於事曰慣說文作遦從辵丑略反貫聲也經文有作串俗字也非正體也）。

Accustomed and practiced (慣習: for 慣, the fanqie is 卦患 [guàn]. Already explained in the previous fascicle 438. The Erya says: '慣 means practiced.' Being long practiced in a matter is called 慣. The Shuowen writes it 遦, taking radical 辵 with 貫 as phonetic. The sūtra text sometimes writes 串, a vulgar character, not the orthodox form).
