Comment: The meanings vary greatly, but generally imply some small thing: Lezg. "a small piece of wood"; Tab. "trigger (of a gun)"; Rut. "dung (of sheep)" (cf. also Rut. Khniukh. ḳerḳel id.); Tsakh. "ankle"; Kryz. "dung (of a donkey, horse)"; Bud. "small lumps".
An expressive reduplicated stem (*-ṭ should probably be treated as an expressive suffix); all the listed forms are quite impossible to separate from each other, thus the supposition that Lezg. ḳerḳeṭ and Tsakh. ḳerḳeṭ are borrowed from Arm. k:ǝrk:it: "hard" (Виноградова-Климов 1979, 158) is obviously wrong.
