Sendoff → It is formed from "send" (from Old English "sendan", meaning to cause to go) and "off" (meaning away or from). The word "sendoff" refers to the act of sending someone away, often with a farewell gesture.
Think of the action of 'causing to go' ('send') someone 'away' ('off') — that's why a sendoff is a farewell when someone is leaving.
