Akkadian

papallu - shoot, offspring (CAD P 105, AHw. 823)

Var. pamallu. Evidently related to Sum. pa-pa-al “shoot, offspring”. The Sum. word is always written syllabically and has no internal etymology (unless the first element is related to Sum. PA “branch, leaf”). It may well be of foreign origin. Cf. Landsberger 1967b:19, fn. 59 where both the Akk. and the Sum. words are considered “ursprachlich”.
