A more thorough explanation:

A barrister is a type of lawyer in the United Kingdom and some other countries. They are different from solicitors, who give general legal advice, because barristers specialize in representing clients in court.

• When someone is accused of a crime in the UK, they might hire a barrister to represent them in court.
• In some countries, like Australia and Hong Kong, barristers wear special robes and wigs when they appear in court.

These examples show how barristers are lawyers who focus on representing clients in court. They are often hired by solicitors to handle the court proceedings for a case. In some countries, barristers have a specific dress code when appearing in court.
