Proto-Lezghian: *q:I[ɨ]lq:I-
Meaning: sheep's dung
Tabasaran: ʁirʁil
Agul: R̀ülR̀-an
Comment: Cf. also Tab. Düb. q:ilq:il id.; with irregular metathesis and an expressive suffix probably also Ag. Burk. q:üšq:el ( < *q:uIlq:-aš) "horse's dung". An expressive reduplicated root, but having probable external parallels.
