Thread:User talk:Rua/*(hₓ)yḗkʷr̥

Hello, about the roll-back in the PIE term *(hₓ)yḗkʷr̥. Fortson reconstructs it as an acrostatic with a lengthened e grade, so does James Clarkson. Neither Beeks nor Sihler mention the ablaut but they reconstruct them with a short e grade. Plus none of them add a laryngeal at the beggining.
