Akkadian

damāšu - to wipe; to cover (AHw. 156, CAD D 64)

See also dumšu 'a wiping cloth; a coverlet' (AHw. 176, CAD D 183). Akkadian words are to be compared to the widespread Ethiopian root *dmš. Von Soden (AHw. 156) compares the Akk. verb with Arb. dms 'to become heavy, strong (darkness); to bury; to cover, to conceal', to which one should add Gez. damasa 'to cover, to hide' and, most probably Mhr. hədmōs 'to dip', Jib. edmís 'to dip', Soq. édmes 'to plant tree spalings into a hole'. In fact, the two sets of meaning (“to wipe out” and “to hide”) need not be mutually opposed and may well be combined within one lexeme, see the discussion in EDA II.
