It very clearly states that since 1918 the american spelling has been 'extrovert'. That has nothing to do with whether the A or O is correct, only that O is more common in American English.

It also says she changed the definition, that's the nature of language, it evolves. That can be through a colloquialism, a hard change (as this seems to be), or many other reasons.

I am not arguing whether it is correct or not, I am simply saying it is different.

Maybe I'm tired but this comment reads to me as if you're disagreeing with me when everything you say supports what I said? My objection/question was how you came to the conclusion it's a US/UK thing. There's no support for that in the article.

We can both be tired, it's OK.

I based it on this

Thanks to Phyllis Blanchard ExtrOversion is the prominent spelling of the word in the United States today.

In her 1918 paper, "A Psycho-Analytic Study of August Comte" she writes:

"In order to understand the marked contract between Comte's mental attitude during his early years and that of his later life, we must keep in mind Jung's hypothesis of the two psychological types, the introvert and extrovert, -- the thinking type and the feeling type."

Not only did she change the spelling of the word, but she also changed the definition!

That's what I'm saying! It does not say anywhere that it's spelled extrAverted in the UK. If anything it says the exact opposite.

According to the Oxford English Dictionary, "The original spelling 'Extravert' is now rare in general use but is found in technical use in psychology."
