Comment: As a case marker PL *-q(a) usually denotes location behind, but can be also used as a possessive case (the same development is characteristic also for Andian parallels). Somewhat problematic is relating here the Arch. translative case in -χ-ut ('through smth.') and the comparative case in -χ-ur. See Alekseyev 1985, 54.
PL *q(a)- is also used as a preverb ('back, behind': Tab., Ag., Rut., Tsakh. q-; possibly also Lezg. -χ- with the meaning of repetitiveness ('once more'), see Alekseyev 1985, 121).
