When an unmarried couple splits up, the person who makes more money will sometimes help their former partner financially — this is called palimony.
After a divorce, a former husband or wife is often required help support an ex-spouse who earns less money. The name of this legal agreement is alimony, from a Latin root, alimonia, or "nourishment." Alimony has been around for hundreds of years, while the newer palimony wasn't coined until 1979. Palimony is still fairly uncommon, and the term includes the general division of money and other assets when a couple separates.
