PROTO: *rŏlʔi (~-ɫ-,-ɦ-)
MEANING: dirt, mire, pus
COMMENT: Reconstructed for the PEC level. In Lak. there occurred an assimilation (lal < *ral), and in Rut. - a metathesis (lar < *ral), quite natural for a root with two different liquids. The original structure is very well preserved in PD (where *d- < *r-) and PN. In general the comparison seems quite plausible both phonetically and semantically. Perhaps we should also add (with metathesis): Akhv. ħara 'faeces'.
