Incorrect spelling, explanation: the correct spelling is occasions because it matches with the original Latin form – occasio(n-). It hasn’t got the double -s consonant, only double -c. This noun is a plural of the word occasion. Occassions is thus a wrong form and the right one is occasions.

Correct spelling, explanation: occasions is the only right spelling, because of its etymology. The Latin form includes the double -c, not the double -s. This noun must be written in accordance with its root. Therefore, the only correct version is occasions, not occassions.

Definition of occasions:
noun, reasons, causes
I’ve had many occasions to complain and now I’m finally going to do it.
