Proto-Dargwa: *dumb
Meaning: edge, bank
Akusha: dub
Chiragh: dum
Comments: Cf. also Ur., Mek., Kharb. dub 'bank'. From the same root is obviously formed Ak. dub-ura, Chir. dab-ura 'mountain'. Although the Chir. form here has lost the nasalization, its former presence is securely confirmed by an old Archi loanword from Darg.: Arch. dumpǝra 'hill'.
