"Princeton packs many charms into its 18.4 square miles. Halfway between New York and Philadelphia, it has long attracted affluent professionals, many enduring commutes of more than an hour in return for roomy, historic houses, old-growth trees that burst into flower in spring and the cultural riches of Princeton University." — Julie Lasky, The New York Times, 21 Apr. 2021

Visualize with us: coffers overflowing, a cash flow more than adequate, assets that are fluid, an elderly duck in a top hat diving into a pool of gold coins. The images conjured reflect the essence of the word affluent. Based on the Latin verb fluere, meaning "to flow," affluent is all about flow. (The same image is echoed in other fluere descendants, such as confluence, fluctuate, fluid, influence, mellifluous, and superfluous.) The flowing of goods or riches wasn't the word's first concern, however; 16th century print examples of affluent tend to be about the abundance of such intangibles as "goodness" and "spirit." In the 17th century, the flow suggested by affluent varied greatly: streams, poisons, estates, and blood were all described with the word. In modern use, affluent most often describes wealthy people (or ducks), or places where wealthy people live.
