COMMENT: The type of laryngeal in the cluster -Hn- can not be established precisely, because in two critical cases (PD and PL) the root underwent an influence of *nĕmʒ_i 'louse' (PD *neṭ - cf. PD *nez 'louse'; PL *näṭ - cf. PL *näc̣: 'louse'). All other correspondences are regular, and the root can be safely reconstructed for PNC.
