Unsparing → It is formed from "un-" (meaning not) and "sparing" (from Old English "spearcian", meaning to be frugal or to save). The word "unsparing" means not being frugal or generous, often in the context of giving or showing mercy.
Think of 'not being frugal' ('un-') and 'being generous' ('sparing') — that's why unsparing means to give freely without holding back.
