A more thorough explanation:

Latinarius A Latinarius is a person who interprets Latin. In history, Latin was a widely used language for communication and documentation. However, not everyone could understand Latin. That's where a Latinarius came in. They were trained to interpret Latin for those who couldn't understand it. - During the Roman Empire, a Latinarius would be needed to interpret official documents written in Latin for people who spoke other languages. - In a modern-day Latin class, the teacher could be considered a Latinarius as they are interpreting the Latin language for their students who are learning it for the first time. These examples illustrate how a Latinarius would be used in different contexts throughout history and in modern times.
