The eight-letter word "affluent," beginning with the letter "a," is a synonym for the word "wealthy." An affluent person is someone who has a lot of money, possessions or wealth. The term "affluent" stems from the Latin word "affluere," which means to abound in.
In marketing, researchers refer to people who make more than $100,000 or more per year as affluent and those who make more than $500,000 or more per year as wealthy. However, an individual's income must be compared to the location where they live as the dollar will buy much more in some cities compared to others.
