Akkadian

dūru - (city) wall (AHw. 178, CAD D 192)

See also dūrāniš ‘over the walľ (AHw. 177, CAD D 190). The underlying semantic development is, most probably, from ‘what surrounds, encircles’ (Marrassini 1971, 49f.). A derivation from the secondary meaning ‘to dwell (’(walled) dwelling space’) is not to be ruled out completely (if accepted, at least some of the WS nominal derivations with the meaning “dwelling” listed here may be directly related to Akk. dūru). Still another semantic derivation, discussed in Buck 1949, 473 for Germanic words for “wall” (Gothic -waddjus, German Wand), is from “to turn, to plait” as referring to a wall of wattle-work.
