巢窟（上仕交反禮記云夏則居曾巢史記上古巢居穴處也說文鳥在木曰巢從木象形也下坤骨反杜注左傳云窟地室也古今正字從穴屋聲亦作掘）。

Cháokū (巢窟, nest and lair; the first character is fanqie 仕 + 交. The Liji says: "In summer they dwelt in layered nests." The Shiji says: "In high antiquity, they nested in trees and dwelled in caves." The Shuowen says: "A bird in a tree is called cháo; it is derived from the wood radical and is pictographic." The second character is fanqie 坤 + 骨. Du Yu's commentary to the Zuozhuan says: "A kū is a subterranean room." The Gujin zhengzi gives it as with the cave radical and the phonetic wū [屋]; it is also written as jué [掘]).
