Etymology

Origin of deficit

First recorded in 1775–85; from Latin dēficit “(it) lacks,” 3rd-person singular present of dēficere “to fail, run short, lack, weaken”; deficient

Explanation

If you're running a deficit, you are losing. You might be losing money or losing a game. Either way, you better make up for it. When the government runs on a deficit, often the loss can be offset by a raise in taxes. If you have a deficit of iron in your body, you should consider eating more spinach. The word deficit comes from the Latin deficit meaning "it is wanting." A deficit is characterized by the wanting of something missing.
