I cannot spell 'manoeuvre' for the life of me. Granted, it's spelled as maneuver to Americans, which is a lot easier given that there aren't three vowels in a row, but someone who helped create spelling decided it was a brilliant idea to throw in an O into random words completely unnecessarily. The U I get (favourite, colour, parlour, etc), but random Os? No. Like. Just why. No wonder Americans took them out. They're dumb. Foetus? Oestrogen? MANOEUVRE?!?!? Come on.

But yes, that's one word I have never been able to spell. Without fail, I get it wrong every time unless I've just looked up the correct spelling. xD Sometimes other words I mess up are where it could be an a, but it's an e. Or vice versa.

Are there any words that just mess with you every time, despite how diligently you try to get them right? I used to have it with privilege (I'd always throw in a d), but I overcame that. XD
