Synonym discussion
Sense: noun/1
Falling-out, quarrel, rift, fallout, and break-up all describe relationships going wrong, but they focus on different stages and types of damage. A quarrel is the argument itself, often a short spoken clash. A falling-out is the damaged relationship that follows, especially when two people stop being warm or friendly after that clash. A rift suggests a deeper and longer division, sometimes between families, teams, or political groups. Fallout is more formal and often points to the negative results of a dispute, not just the broken friendship. Break-up is mainly used for romantic relationships. A minor quarrel can pass quickly, but a serious quarrel may grow into a falling-out and later become a lasting rift.

Etymology
This noun grew out of the phrasal verb 'fall out', which has long been used for people coming into conflict with each other. In English, 'fall' can describe moving into a new state, while 'out' often suggests separation or no longer being together. That combination produced the idea of people moving out of harmony. The hyphenated noun 'falling-out' later became a way to name both the quarrel and the damaged relationship that follows it.
