Tam tells us what it’s like, though I suspect we’ve all been through it more times than we’d admit:
The brain tells the fingers to type “capitol” or “principal”, and they wind up typing the much more frequently-used “capital” or “principle”, and the brain never notices because it’s halfway into the next sentence. I usually catch this in proof-reading, but sometimes it’s early and you haven’t had any caffeine and you just want to get something up on the blog before you’re off to do other, more chore-like things, and you walk away from the keyboard leaving a hanging curve belt-high over the plate. Sigh.
The operative phrase here, of course, is “I usually catch this.” Which makes it that much worse when you don’t. And you may be certain that your
spearchucker spellchecker won’t notice; it’s the wrong word, but by damn, you spelled it correctly.
If I had a dime for every horrible thing I saw on this page after hitting the Publish button, I could probably pay my hosting bill for the next year.
