√pA3 'rise against'
BR. refer to such a root certain forms from the reduplicated middle stem pipI with prefix ud. Since, however, such forms occur with the unquestionable meaning 'drink', and, on the other hand, forms from ut-piba (ÇB.) with the meaning given to 3pA, it seems probable that we have here only a curiously specialized use of √1pA + ud.
