"Orientated" is correct usage in the U.K. version of English:

I partly feel embarrassed to have been wrong after all, and partly feel relieved that everyone hasn't just been losing their minds in recent years.

There's another one that everyone's been sticking an extra syllable in that I would check...if I could think of it.

Are you thinking of "aluminium", the U.K. version of "aluminum"?

No, I know about that one. There something else with an extra -at- syllable that I encounter often enough that I'm surprised I haven't just run into it again since I made that comment.
