Proto-Nakh: *=āc-
Meaning: 1 to mow 2 to work hard, be exploited
Chechen: =āc- 2
Ingush: =ac- 2
Batsbi: =ac- 1
Comments: A PN derivate is *cēl 'hoe' ( < *'sickle, scythe'), reflected in Chech. cel (cēla-), Ing. cel; however, Bacb. cel 'scythe' is rather to be considered a loan from Georg. celi 'scythe'.
