Proto-Tsezian: *Lãcu ( ~ *L:-)
Meaning: bug, bed-bug
Tsezi: ʎacu
Bezhta: giʔis-naco
Comments: The component giʔis- in the Bezht. compound is not clear. Khaidakov 1973 cites Gin. naco "bed-bug", but the standard Gin. word is tawsa; thus, this is either a loan from Bezht., or more probably a mistake (Gin. instead of Bezht.).
