Etymology

deficiency = de<away, down> + fic<make, do> + ency<noun suffix>

  • de (from Latin de-, meaning "away, down")
  • fic (from Latin facere, meaning "to make, do")
  • ency (noun-forming suffix indicating a state or condition)

Etymology Origin:
The word "deficiency" traces back to Latin deficientia, derived from deficere ("to fail, desert, or run short"). The morpheme de- implies reduction or negation, while fic (from facere) conveys action or creation. Combined, they suggest a "failure to make/do enough." Over time, the term evolved in Middle English via Old French to describe insufficiency in both tangible (e.g., nutrients) and abstract (e.g., flaws) contexts.
