Which is the proper spelling: “disfunction” or “dysfunction”?

Is this word spelt dysfunction or disfunction?
Are there any correct spellings at all for this word?

The reason I asked is because I’ve always learned to spell it as “disfunction” until recently, when I realized I’m starting to see more of “dysfunction”

Answer

Dysfunction is by far the more common according to Google Ngrams
