Proto-Lezghian: *lojc: / *jolc:
Meaning: 1 clay (for plastering walls) 2 white
Lezghian: luʒ (Nüt.) 1
Tabasaran: lurz 1
Agul: luz 1
Rutul: lɨz 1
Kryz: luzu (Al.) 2
Budukh: luzu 1
Comment: Cf. also Tab. Khan. jülʒ 'clay' (demonstrating the original *j; the lit. form lurz (as well as Ag. Bursh. lurz) is obviously a development < *lolc: < *lojc: with assimilation); Rut. lɨzɨ-d 'dough'. The Kryz. word is a result of contamination with PL *lac:V- 'white' (q.v.), reflected as läzi in Kryz proper. The closely related Budukh language makes a clear distinction between lǝzu 'white' and luzu 'clay'.
