The verb, etymologically identical with bâˀu “to go along”, is, however, attested in Mari with a different thematic vowel (ū vs. ā) and displays a different meaning (“to come” vs. “to pass, to go along”). The cumulative evidence of the vowel, the meaning and the dialectal distribution makes it almost certain that these examples should be interpreted as attestations of the WS root *bwˀ “to come”.
