A more thorough explanation:

An agent is someone who is given permission to act on behalf of another person, known as the principal. This relationship can be created intentionally or through actions.

• A real estate agent is authorized to act on behalf of a homeowner to sell their property.
• A power of attorney gives an agent the authority to make legal and financial decisions for someone who is unable to do so themselves.
• A sports agent represents a professional athlete in contract negotiations and other business matters.

These examples illustrate how an agent is authorized to act on behalf of someone else in a specific context. The agent has a duty to act in the best interest of the principal and follow their instructions.
