COMMENT: One of the cases with the interesting correspondence PEC *χHw : PWC *Łʷ. It is not yet clear what should be reconstructed in these cases: perhaps, some cluster like *χl- or *lχ-. It is also possible that in some cases PAT l- is a result of secondary lateralisation, and Ub. w : PAK *ħ could also point to PWC *χ́Iʷ (for which otherwise no examples are found). Most of the EC languages point to the PEC oblique base *χ_Hwĕj-rV- (cf. PN *pħare-, PA *χʷor-, PD *χ:ur-, PL *χ:ʷäjrV-); in some languages (Shakhdagh, Khin.) the former oblique base became direct. See Trubetzkoy 1930, 277, Abdokov 1983, 123.
