Etymology

incorrigible = in<not> + corrig<correct> + ible<able to>

  • in: Prefix meaning "not" (from Latin in-).
  • corrig: Root derived from Latin corrigere ("to correct, set straight").
  • ible: Suffix meaning "able to" (from Latin -ibilis).

Etymology Origin:
The word traces back to Latin incorrigibilis, combining in- (negation) + corrigere ("to correct") + -ibilis (capability). It entered Middle English via Old French, retaining its core meaning of "uncorrectable." The term originally described moral or behavioral flaws resistant to reform, later expanding to habits or traits deemed unchangeable. The logic follows: corrigere (to straighten) → inability to be straightened → stubbornly persistent.
