A more thorough explanation:

Innocuae utilitatis is a Latin term that means "useful without harming." It refers to an action that benefits one person without causing harm to anyone else.

• Donating blood is an example of innocuae utilitatis because it helps someone in need without causing harm to the donor.
• Volunteering at a soup kitchen is another example of innocuae utilitatis because it provides food for the hungry without harming anyone.

These examples illustrate the definition of innocuae utilitatis because they show how an action can be beneficial to one person or group without causing harm to others. In both cases, the person or group receiving the benefit is in need, and the person providing the benefit is doing so willingly and without causing harm to themselves or anyone else.
