See note DJBA for rejection of the meaning 'dung' and see note to pdr n.m. However, the DJBA argument is circular and to be rejected because in fact the word occurs as "dried dung" at Nid 28a(11) where DJBA has, however, emended it away to פרדא. Also see note to pdr #1. As shown by H. Mutzafi, Leshonenu 80:3(2018):290f., the form פידרא is also supported by Ma’lula Neo-Aramaic.
