Etymology

fallibility = fall<deceive/err> + ibility<capacity for>

  • fall<deceive/err>: From Latin fallere ("to deceive, disappoint, escape notice"), related to fallo ("I deceive"). Retains the core idea of error or failure.
  • ibility<capacity for>: A noun-forming suffix derived from Latin -ibilitas, indicating the quality or state of being capable of something (e.g., possibility, flexibility).

Etymology Origin:
The word traces back to Late Latin fallibilitas, combining fallibilis ("liable to err") and the abstract noun suffix -itas. It entered English in the 15th century via Middle French, reflecting the philosophical concept that human judgment is inherently imperfect. The morphemes fall- and -ibility logically merge to express "the capacity to err."
