non-fungible

American  
[nahn-fuhn-juh-buhl] / ˌnɑnˈfʌn dʒə bəl /

adjective

  1. not interchangeable or substitutable with another of its kind; unique. See also NFT.


Explanation

In economics, when something is non-fungible, it can't be broken into units and interchanged for something else of the same value. Unlike money, things like antiques, cars, houses, and artwork are non-fungible. Non-fungible is frequently used in the term non-fungible token, or NFT, a kind of cryptocurrency. The difference between these and other digital payments is their uniqueness — they can't be substituted. Money is fungible because you can exchange a $20 bill for four fives. A car, however, is non-fungible: you can't borrow your friend's Honda and return a different Honda of the same value. Fungible is from the Latin fungi vice, "to take the place of."
