How it's used

This term carries a formal, slightly literary weight despite being used in spoken contexts to describe serious conflicts. It implies a significant breakdown in a previously stable or friendly relationship, rather than a minor disagreement. It is most frequently applied to public figures, organizations, or countries, though it can describe interpersonal conflicts when the speaker wants to emphasize the severity of the fallout.

Examples

Why did you two become enemies?

Common phrases

relations have turned sour

Common mistake

Learners often mistake this for a casual argument, but it implies a more permanent or deep-seated hostility. It is not suitable for describing a simple spat or a temporary misunderstanding between friends.
