亘然（柯鄧反方言云亘竟也毛詩傳云亘徧也古今正字急引也通度也從二從舟也今作亘俗字也）。

亘然 (fanqie: 柯 + 鄧; the Fangyan says: "亘 means spanning to the end." The commentary on the Mao Odes says: "亘 means pervasive." The Gujin zhengzi says: "Urgent pulling; stretching across. It is classified under 二 and under 舟." Writing it nowadays as 亘 is a vulgar character).
