I suppose you have noticed, I'm not perfect in English. The spell check function is a blessing. A word is red underlined; right click with the mouse and the machine makes a suggestion. Mostly it's easy and works well, but sometimes, I don't understand a bit!
As I wrote about my latest experiences in my bog, among other things, I had some problems to spell the world disease.
The most amazing suggestions came out, everything but the right world. I tried several combinations of s, c, e, i until I finally got the idea of putting an a in it. Than the spelling machine found the right world. I'll tell you some of the suggestions, many worlds are unknown to me: (OK, I didn't seriously thought that all of them could be the right way to spell it, after a few attempts it became a funny kind of game, to try as many possibilities I could think of and watch what came out)
sidepiece, dissidence, decide, despise, diciest, device, demise, decisive, disuse, disguise, dissed, diereses, diesel, dissed, dies ice dies-ice, dices, dissect
And note I made no weird kind of spelling, just any possible combination of d + i/e/ie + s/c + i/e/ie+ s/c as it sounds.
