Notes: PTs has not preserved the original verb, but only the derivate (with a widely spread semantic shift 'break, cut' > 'wound'); note the prefix coincidence in PTs and Laki. The EC-WC comparison see in Абдоков 1983, 162.
Cf. also Urart. iwχ- (spelled iBχ-) 'to destroy', see Diakonoff-Starostin 1986, 60.
