Proto-North Caucasian: *pǝ̆lpV
Meaning: dirt, clay, dust
Notes: A reduplicated root with somewhat irregular correspondences: secondary voicing in PWC, secondary glottalization in PD and secondary pharyngealization in Eastern Daghestan languages (Western forms do not reveal any trace of lost laryngeals). Nevertheless, the root seems reliable, and the irregularities are probably due to its expressive nature.
