A more thorough explanation:

Definition: Relatrix (ri-lay-triks) is an old-fashioned term that refers to a female relator.

Example: In medieval times, a relatrix was a woman who acted as a legal representative for someone in court. She would present their case and argue on their behalf.

Explanation: The term relatrix is not commonly used today, but it was once an important role for women in the legal system. The example shows how a relatrix would have been responsible for advocating for someone in court, much like a lawyer does today.
