1.
breakdown; rupture; collapse
The complete failure or collapse of negotiations, talks, or a relationship, where no agreement can be reached and the parties go their separate ways.

決裂 is a noun that also functions as a suru-verb (決裂する). It describes a definitive, usually irreversible breakdown — stronger than simply "not reaching an agreement."
COMMON COLLOCATIONS:
- 交渉が決裂する (negotiations break down)
- 会談が決裂する (talks collapse)
- 決裂に終わる (to end in a breakdown)
- 決裂に至る (to reach a point of breakdown)
USAGE NOTES:
This word is most commonly seen in news reporting about diplomatic, business, or labor negotiations. It implies finality — the discussions are over and no compromise was found.
