Largesse is a somewhat formal word that refers to the act of giving away money or the generosity of a person who gives away money. It can also refer to the money that is given away.

// The community has benefited greatly from the largesse of its wealthiest family.

"Over the years, ShelterBox USA, an outgrowth of the Rotary Club and named for the relief boxes it distributes, has helped nearly 3 million people in some of the world’s worst disaster zones. It hands out basic survival needs: tents, tools, and household supplies. Twice the organization has been nominated for the Nobel Peace Prize for its life-preserving largesse." — The Olney (Texas) Enterprise, 20 Mar. 2025

The English language has benefited from the largesse of Anglo-French, through which a generous number of words have passed; examples range from simple to account to desert. English speakers owe Anglo-French a huge thanks, in particular, for its adjective large. That word, meaning "generous, broad, or wide," is the source of both largesse and the familiar duo of large and enlarge. Most people understand enlarge to mean "to make larger," but a less common sense (used in Shakespeare's Henry V) is "to set free." Largesse also contains the notion of freedom, specifically with regard to a lack of financial constraints: it's not about having a "large" amount of money but rather being "free" with it. Incidentally, the English word large wasn't about size when it was first adopted in the 13th century. Back then it meant "lavish."
