A more thorough explanation:

Definition: A gestor is a person who carries on a business or manages affairs on behalf of someone else. This term comes from Roman law.

Examples:

• A real estate agent is a gestor who helps people buy and sell properties.
• A financial advisor is a gestor who manages investments and provides financial advice to clients.
• In Roman law, a negotiorum gestor was a gestor who managed the affairs of someone who was absent or unable to manage them themselves.

These examples illustrate how a gestor is someone who takes on the responsibility of managing a business or affairs for someone else. They may have specialized knowledge or expertise in a particular area, such as real estate or finance, and use that knowledge to help their clients achieve their goals.
