What is the etymology for atonement?

The Word "atonement" comes from the Middle English "at onement," meaning "at one" or "reconciliation." It combines "at," meaning "in" or "on," and "one," which suggests a state of unity or harmony. The term evolved to refer to the act of making amends or reconciling, particularly in a religious context, for offenses or sins. Its usage has since broadened to encompass any form of reconciliation or compensation for wrongdoing.
