Difference Between “Disfunction” and “Dysfunction”

Disfunction is a term that is occasionally used to signify a lack or reversal of function. However, it is not widely recognized in formal English, and its usage might be attributed to a misunderstanding or misspelling of dysfunction.

Origin of Disfunction
