Munificence
Etymology
From Latin "munificus" (generous), combining "munus" (gift, public duty) and the root of "facere" (to make) — literally "gift-making." The same "munus" underlies "municipal," "remuneration," and "immunity" (freed from duty). Over time the word narrowed from civic obligation to sheer open-handed generosity.
noun · /myoo-NIF-ih-sunce/
Great generosity, especially in giving lavishly.
What it names
A handle for giving on a grand, almost theatrical scale — larger and more public than everyday kindness.
Example
The library’s new wing stood as a monument to the industrialist’s munificence.
Related idea
Where generosity can be quiet and small, munificence is generosity at scale — grand, visible, and often institution-building.
