Proto-North Caucasian: *š_iḳV / *ḳ_išV ( ~ ś)
Meaning: sweetbrier
Notes: An And-Lezg. isogloss (involving a metathesis, but nevertheless rather reliable). In PA we have weak *ḳ instead of *ḳ: according to a local rule (ḳ: in Av.-And. languages does not occur before fricatives and affricates, tending in this position to pass tenseness to the next consonant).
