慣習（關患反爾雅慣習也言久習於事曰慣從心貫聲也左傳作貫說文從辵作遦同經作串俗字也）。

慣習 [Habituated and accustomed] (Guan + huan fan. The Erya says: '慣 means accustomed.' Being long practiced in an affair is called 慣. It is from 心 [heart] with 貫 as phonetic. The Zuo zhuan writes it as 貫. The Shuowen writes it with 辵 as 遦, which is identical. In the sūtras it is written as 串, which is a vulgar character).
