A more thorough explanation:

Notae

Notae are shorthand characters used in history. They are symbols that represent words or phrases. Notae were used by scribes to write quickly and save time.

One example of notae is the Tironian notes. These were shorthand symbols used in ancient Rome. They were created by a man named Tiro, who was a secretary to Cicero. Tiro created these symbols to help him take notes quickly during speeches and meetings.

Another example of notae is the shorthand used by medieval monks. They used symbols to represent words in Latin. This helped them copy books quickly and accurately.

These examples illustrate how notae were used in history to save time and increase efficiency in writing. They were used by people who needed to take notes quickly and accurately, such as scribes, secretaries, and monks.
