I dont know why nobody has discussed this on this forum before. But broken plurals are only found in Arabic, old south arabian,msa and ethiosemetic lanaguges and not in aramaic or Hebrew/Phoenician. There's probably no more slam-dunk proof of the existence of cushitic people in the early arabian penisula than this. All those ancient north and south arabian inscriptions have broken plurals.
