WORDS I DON'T REALLY KNOW HOW TO SPELL

I won some spelling bees and still these little fuckers get me every time
  1. Maintenance
    I got it that time but not every time
  2. Surgery
    My phone had to autocorrect that for me
  3. Cheesy
    Cheesy/cheesey?
  4. Definitely
    I let autocorrect help me every time with this one
