Improvident is a formal word used to describe something that does not foresee or provide for the future, especially with regard to money. An improvident relationship, habit, or practice is financially unwise or impractical.

“The problem is worst in affluent countries like the U.S., where more than two hundred pounds of food per person get thrown away each year. ‘Even modest food waste reductions would translate into considerable cumulative savings,’ Smil observes. Then, there’s the waste that results from improvident eating habits. If photosynthesis has a low conversion rate, feeding crops to animals compounds the problem many times over.” — Elizabeth Kolbert, The New Yorker, 23 June 2025

Improvident describes someone’s actions or habits as being unwise with regard to saving or providing for the future. It’s a formal word, but the behavior it describes is well illustrated by many of the stories people hear or read as children, including some of the world’s oldest. In Aesop’s fable “The Ant and the Grasshopper,” the grasshopper could certainly be called improvident—he spends all summer singing and dancing while the ant works hard to prepare for winter by storing food, and at the end of the short tale is cold and starving. While today improvident is used mostly in the context of money, and those who are irresponsible with it, one can be improvident with other things (such as time or food), even happily. In another children’s tale, The Tale of the Flopsy Bunnies, author Beatrix Potter introduces the titular family of bunnies, sleepy from eating too much lettuce, as follows: “they were very improvident and cheerful.”
