Is there a word, you always spell wrong?

Tergiversation, well, that's my most common one at least. Spellings not really a huge issue for me :(

" Manoeuver. At least the proper version. I can never remember where the O goes. "

Absolutely.
 
I always put absoloutely for some reason. Weird.

rythm i don't really ever use it. but it is still a bitch.

afraide---------------------- Which should be Afraid

I spell a bunch of words wrong.  I'm not the greatest speller in the world.  :(

prestidigitation and mature (which should really be spelled "mateur" given its origin)

Yse

Definitely the word definitely. 

Their, often mispelling it as "thier".
 
And diaar...diarheea...diarhea...diahra-You know what I'm talking about. It's just as bad spelling it. Not that I need to use it very often of course.
