What is that one word that you can never spell correctly on your first try?

Everyone has at least one… you’re trying to type or write a word out, and no matter how many times you’ve spelled it before in your life, you mess it up or at least have to think about it for a second every time.

I have a couple, I always forget whether “occasion” has two Cs or two Ss, and I can never type “couch” without typing cough first. I used to have a lot of trouble with unnecessary too, forgetting which letters you needed to have two of.

What words always trip you up when you’re writing?
