Dysfunction is the correct spelling, while disfunction is a common misspelling—dysfunction means impaired or abnormal functioning of a person, system, or organ.
Have you ever wondered whether disfunction or dysfunction is the correct spelling? You are not alone. Many students, writers, professionals, and English learners search for this question because the two words look almost the same. A single letter can make the difference between a correct English word and a spelling mistake.
