“Philanthropy” means giving money to support a cause or institution, or charitable giving in general. Technically, the word implies that the money is given in the spirit of charity or love as well, and not just as a tax deduction – the word was coined from the Greek words for “love” and “mankind” – but today it’s used in the more generic sense of “giving to charity” without assigning any particular benevolent intent to the giver.
Example: “Even at eight years old, Leah seems to have a natural tendency towards philanthropy; she always shares her sweets with her classmates.”
