Comment: Complicated reflexes in modern languages are due to combinations of class infixes with the Inlaut laryngeal: cf. Tab. iṗu-b (*ʔi-b-ʔ-) / iṭu-b (*ʔi-d-ʔ-); Lezg. praet. ṭü-na (*ʔi-d-ʔu-na) as opposed to the infinitive ne-z (*ʔin-Vs: < *ʔiʔ(ʷ)l-Vs:). The root-final *-l- is well preserved in Rut., Kryz., Bud.; cf. also Ag. Bursh. ʕüṭal-as. On the other hand, the Rut. terminative form li-ʔi-r and the Arch. lah- reflect the metathesized variant *liʔʷä-.
