Proto-North Caucasian: *=i(r)ŁwVr
Meaning: to deceive
Notes: The root structure is best preserved in PD. Avar has reduplicated the root, in PN (Chech.) the initial weak syllable was reduced (*lV- < *=iŁV-). Correspondences between EC languages allow to reconstruct a lateral root consonant *Łw, which corresponds to the lateral in PWC. The only problem is loss of labialisation in PWC (we would rather expect a form like *ĹʷV), which happens also in a number of other verbal roots - perhaps as a result of phonetic interaction with former class markers. See Абдоков 1983, 158.
