坎窟（上堪感反埤蒼坎埳也下坤骨反杜注左傳云窟地室也古今正字云窟狐兔所伏處也從穴屈聲或從土作𡑣或從石作𥖚並通也）。

坎窟 (*kǎnkū*, pit and cavern; the upper character has the fanqie 堪感 [*kān* + *gǎn*]. The *Picang* says: "*Kǎn* is a pit." The lower character has the fanqie 坤骨 [*kūn* + *gǔ*]. Du's commentary on the *Zuo zhuan* says: "A *kū* is an underground chamber." The *Gu-jin zhengzi* says: "A *kū* is a lurking place for foxes and rabbits; it is composed of 穴 with 屈 as phonetic." It is also written with the earth radical as 𡑣 or with the stone radical as 𥖚; both are acceptable).
