If you show someone kindness or generosity, that's beneficence like when you shovel a neighbor's sidewalk or mowing the lawn just to help out, no strings attached.
Beneficence comes from the Latin word benefactum, meaning "good deed." That's exactly what beneficence is — helping someone just because you care, not because you want to be praised for being nice. Giving your time, skills, or even a donation of money or items shows beneficence. This word can also describe the character of a person who is helpful, caring, and compassionate.
