Apparation or Apparition?

[Minx]

Hello all, I have a conundrum that I cannot solve...In the HP books, Apparition is the study of Apparating right?

So why does JK make an obvious mistake (in my eyes) and call it Apparition instead of Apparation? If we look at definitions, apparition is 'the sudden appearance of a GHOSTLY figure' But since we all know a person apparating into view is whole and solid, I think it should be called APPARATION...

(I know that JK created the world so please don't point out that it is author's choice. This is just something that's always bugged me...)

To what gives you the idea that J.K calls it Apparition? Cause it is definitely Apparation.

It's usually spelled "Apparition," with an "i," and only very occasionally will you see it "Apparation" in canon -- and moderated archives generally only accept "Apparition" as the correct spelling. I'd guess that JKR chose "Apparition" because it's a more natural word to say and to read, since it already appears in English with a related kind of meaning. ("Apparation" looks unnatural to me and makes my eye pause and takes me out of my reading for a moment.) For her wizarding vocabulary, JKR often tends to use words, even in her spells, that are already real words or forms of words, even when she's using Latin or Greek base words and Anglicizing them a bit or shmushing them together.
