A more thorough explanation:

Existimatio is a term from Roman law that refers to a person's reputation or standing in society. It was especially important for Roman citizens to have a good existimatio, which meant they were respected and had a high social status.

For example, if a Roman citizen was known for their honesty, bravery, and good deeds, they would have a good existimatio. On the other hand, if someone was known for being dishonest, cowardly, or immoral, their existimatio would be low.

In addition, existimatio could also refer to the decision or award of an arbiter, which was a person chosen to settle disputes between parties. The arbiter's existimatio would be their final decision or judgment.

Overall, existimatio was an important concept in Roman society that reflected a person's reputation and social status.
