Auto-correct has probably ruined my spelling

I just realized that it’s been a long time since I spelled the word “pieces” correctly.

This is because I hardly ever handwrite things anymore, and when I do handwrite things, I don’t ever write “pieces.” When I do it’s on a computer, and usually in Word.

But every time I type “peices” into Word (which comes much more naturally to my fingers), Word uncomplainingly and effortlessly switches the letters around so that the word is spelled correctly.

I think I’d rather have it underline the word and show me that I’m incorrect, because that way I could make sure I spell correctly. So Auto-correct is getting turned off.
