Why has that come up? I used to spell that word superfast when I was kid hundreds of years ago. Who knows my idiot kid reason? - just one of those things - like a parlor trick. Spell the long word really fast. 28 letters I believe. I'm not going to check but I bet that's right. I did it a lot of times and got to have a relationship with that word.
I can still do it. By rote. Spell that word in like 3 seconds. If I haven't lost it by now I will probably die with the ability.
So much junk up in this old brain of mine
