means Money you've set aside rather than spent, kept for future needs or wants.

from From the verb 'save,' which came into English through Old French 'sauver,' from Late Latin 'salvare' meaning 'to make safe,' rooted in Latin 'salvus,' 'safe' or 'unharmed.' So the original sense of saving is rescue — and tucking money away is, quite literally, keeping it out of harm's way. The noun 'savings,' meaning money preserved, grew naturally from this once people started thinking of coins as something that could be rescued from the jaws of spending.
