From Sum. (giš)BA.TUR. A late (possibly, “learned”) borrowing.

baṭālu - to cease, to stop (CAD B 174, AHw. 116)

Derived words: baṭiltu 'interruption' (CAD B 176, AHw. 116); baṭlu 'ceased' (CAD B 177, AHw. 116); biṭiltu (mng. uncert.) (CAD B 297, AHw. 134).

bazahātu - outpost (CAD B 184, AHw. 117)

While the WS origin of this lexeme is relatively certain, its further etymological analysis is severely hampered by the orthographic ambiguity of the signs rendering the latter two radicals (Streck 2000, 85f.).

bazku - quacking (of ducks) (SAD I)

Or basku etc.
Perhaps an onomatopoeic word imitating the characteristic sound produced by ducks.
