Hi Ajaxanon, Here is what you posted on Optilang's Wall: Ajaxanon , 12-15-2008 6:48 PM I am American and so can you! It's interesting reading your responses. Having coffee with a Scottish friend the other day, I noticed that she also said 'disorientated,' which got me thinking. I come from post-British colonialist South Africa, and usually say 'disorientated,' although I noticed that many other South Africans use 'disoriented.' Now living in the US, I'm sure I'm in the minuscule minority of people who say 'disorientated.' It sometimes irritates me when Americans make silly assumptions that the Brits are adding syllables or changing the English language when the roots of English stem way back to the time of the Anglo Saxons and beyond. It also gets me that the metric system is beyond the Americans. Also, having freezing point at zero and boiling point at 100 would help. At least they've adopted the Gregorian calender, otherwise who knows where we would be. So, I guess the verdict is that 'disorientated' is UK (and hence formally correct), and that 'disoriented' is US (and likely a bastardization). I do, however, think that the US version is gaining popularity and likely to replace the older one. C'est la vie.
