The most archaic form for 'brother' is Ud. wiči < *u_-Včɨj ( = PA *woc:i, PN *wašo etc.). Other Lezghian languages normally reflect a contracted form *čʷɨj. The Shakhdagh and Archi forms reflect a suffixed form *čʷɨj-t:V-u_ (for Archi more suitable is possibly a protoform with a double 1st class marker: *u_-Včɨ-t:V-u_ > uš-du). It is interesting to note a specific reduplicated oblique stem in Tab. and Ag.: Tab. č̌ič:̌i-, Ag. čuč:u- (Fit. k:ük:ü, Burk. č:uč:u-), which is reflected also (already as direct) in Tsakh. čoǯ / čož. For 'sister' some Lezghian languages reflect a prefixed stem *r-ɨčɨj ( = PD *ruc:i, Khin. rɨcɨ), thus Rut. riši, Tsakh. jučɨ / jiči, Arch. doš-dur ( < *r-ɨčɨ-t:V-r, with a double class marker as in 'brother'). Most languages, however, reflect a prefixless stem *čɨj (or, with secondary adjectival suffixation, *čɨj-t:V-r, as Kryz., Bud. šidɨr). The Udi form χun-či is a compound with χun(i) 'female). Again, Tab. and Ag. have a reduplicated oblique base: Tab. čič:u-, Ag. čič:i-.
