What does dysfunction mean?
Dysfunction means abnormal or impaired functioning. It applies to anything that is supposed to work in a certain way but does not: an organ, a machine, a relationship, a family or an entire organization. You might read about thyroid dysfunction, family dysfunction or organizational dysfunction.
The word combines the prefix dys-, which carries a sense of “bad,” “abnormal” or “difficult,” with function. Its adjective form is dysfunctional, used for things that are not working properly.
Is “disfunction” a real word?
Disfunction appears occasionally in print, but dictionaries and style guides treat dysfunction as the standard spelling. If you are writing for school, work or publication, use dysfunction and avoid the variant.
The variant exists because many English words begin with dis-, such as disagree and disappear, so the spelling looks natural. Looking natural is not the same as being standard, and the safe choice is always the dys- form.
Is “dsyfunction” a real word?
No, “dsyfunction” is a typo, not a word. The letters s and y have been swapped; the correct order is d-y-s. Spell-checkers will flag it, but it is worth knowing so you can spot it in your own drafts.
Disfunction vs dysfunction: which spelling is correct?
Dysfunction is correct, and the reason is the prefix. The prefix dis- usually means “apart,” “not” or “opposite,” as in disagree and disconnect. The prefix dys- means “bad,” “abnormal” or “difficult,” as in dyslexia, dystopia and dyspepsia.
- dys- (bad, abnormal, difficult): dysfunction, dyslexia, dystopia.
- dis- (apart, not, opposite): disagree, disappear, disconnect.
Because dysfunction describes something working badly, the dys- prefix is the one that fits.
Does dysfunction only describe health problems?
No. Dysfunction is common in medical writing, but it also describes relationships, families, teams, governments and software. A dysfunctional meeting, for example, is one that fails to do its job. The idea is the same in every case: something is not working as it should.
