A more thorough explanation:

Definition: Bonum factum (boh-nuhm fak-tuhm) is a Latin term that means a good or proper act or deed. It is often abbreviated as b.f. or referred to as bene factum.

Examples:

• Donating money to a charity is a bonum factum.
• Helping an elderly person cross the street is a bonum factum.
• Volunteering at a local shelter is a bonum factum.

These examples illustrate the definition of bonum factum because they all involve doing something good or proper for others without expecting anything in return. They are acts of kindness and generosity that benefit society as a whole.
