PWS
*ṣ̂VpardVˁ- - frog (SED II No. 222; Kogan 2011: 210)
It is only the Hbr. form that reflects the original quinqueconsonantal base, reduced to *ṣ̂VrdVˁ- in Aramaic and *ṣ̂VpdVˁ- in Arabic and MSA. Alternatively, two unrelated quadriconsonantal terms can be postulated for PS with their subsequent contamination in Hebrew.
