The end of a romantic relationship or friendship between people.
After their breakup, they decided to remain friends.
Breakup → It is formed from "break" (from Old English "brecan", meaning to shatter or destroy) and "up" (meaning to a higher position or state). The word "breakup" refers to the act of shattering a relationship or connection, often leading to separation.
Think of 'breaking' something into pieces ('break') and 'up' suggesting a change to a new state — that's why a breakup means the end of a relationship.
