Comment: The oblique base must be reconstructed as *c̣ojɨ- with Ablaut (cf. Lezg. c̣u-, Khl. jɨc̣ɨ-, Tab. c̣i-, Ag. c̣i-, Rut., Kryz. c̣ɨ-; with vowel levelling Tsakh. c̣ajɨ-, Bud. c̣ǝji-). There also must have existed a parallel *-r-base *c̣o(j)-rV-, cf. Arch. loc. c̣ere-qI and the Udi a-r-uχ (originally a plural form). 4th class in all class-distinguishing languages.
