A more thorough explanation:

Definition: A repudiator is someone who rejects or refuses to accept something, especially a contract.

Example 1: John signed a contract to sell his car to Sarah, but he changed his mind and refused to go through with the sale. John is a repudiator.

Example 2: The company agreed to deliver the goods to the buyer on a specific date, but they failed to do so. The buyer can now be considered a repudiator if they refuse to accept the goods at a later date.

The examples illustrate how a repudiator is someone who goes back on their word or agreement, causing a breach of contract. It is important to honor agreements and contracts to maintain trust and integrity in business and personal relationships.
