But what does Kal-El means... I really haven't got the time to write a whole article about that, I'll tell... Now, Superman was first written by 2 Jewish guys during our nation's hardest time in recent history. "Kal" in Hebrew means either" Easy" or "lightweight", the word "EL" actually means "God" or "To" Make the math yourself of how many meanings this name has. Personally I think they meant "Lightweight-God" to emphasize the near-god quality of Superman. Happy jewish new-year everyone!!
