A more thorough explanation:

Definition: Irremediable breakdown of the marriage refers to a situation where a marriage has broken down completely and cannot be fixed or repaired. It is also known as irretrievable breakdown of the marriage.

Example: John and Jane have been married for 10 years, but they have been having problems for the past few years. They have tried counseling and therapy, but nothing seems to work. They have reached a point where they cannot stand each other anymore and have decided to get a divorce. Their marriage has reached an irremediable breakdown.

Explanation: The example illustrates how a marriage can reach a point where it cannot be saved, despite efforts to fix it. Irremediable breakdown means that the marriage has completely broken down and there is no hope of reconciliation. In the example, John and Jane have tried counseling and therapy, but their problems have persisted, leading to the decision to get a divorce.
