Comment: In Tab., Ag., Kryz., Arch. and Ud. we witness a case of interaction between the root laryngeal (normally reflected as -h-) and the class infix -b- (PL *p:). Cf. the paradigm in Kryz. (inf. lɨpɨ-ǯ < *l-i-b-ʔIʷɨ-, dur. lu-ri, prohib. m-uʔu), Bud. (juʔu, jɨpǝ-ǯi), Arch. (bo-s < *ʔi-p:-ʔIʷɨ-s, dur. wa-r < *ʔiʔIʷa-r without the class infix). In Lezg. and Kryz. there is a *l- preverb; other languages reflect a prefixless form.
