There are some words that I always, without fail, spell wrong while typing... even when I know how to spell them.
take regard for instance...
for some reason I always type it as reguard...
I do not know why. I have made the mistake enough to know what it is by now... but I catch myself doing it all the time (or rather my spell checker does).
Typos are a different thing.
Oh another one is... successfully... that word kills me for some reason. If I stop to think about it, I spell it correctly, but I get it wrong all the time when I am typing along.
There is a few more, but I can not think of them right now.
Are there any that you always misspell? Care to share them with the group? ;)
