A more thorough explanation:

A plaideur is a type of lawyer or advocate who represents clients in court. The term comes from the Law French word "pleader."

• When John was accused of a crime, he hired a plaideur to defend him in court.
• The plaideur argued passionately on behalf of his client, trying to convince the judge and jury of his innocence.
• During the trial, the plaideur presented evidence and cross-examined witnesses to support his client's case.

These examples illustrate how a plaideur is a type of lawyer who specializes in representing clients in court. They use their legal knowledge and skills to argue on behalf of their clients and try to win their case.
