How to spell OCCUSIONALLY correctly?

If you find yourself often mistyping "occusionally", don't fret! The correct spelling is "occasionally". A couple of suggestions to help you remember are to break down the word into syllables (o-cca-sion-al-ly) or think of it as a combination of "occur" and "i-once-in-a-while-ly". Keep practicing, and soon it'll be second nature!
