PYUtativ, Keith

Oh. My. God. I. am. so. prescriptive. But Keith Olbermann just said puTAtive, not once but twice.

But I checked it, and did like this note from the online etymology dictionary, "At first esp. in putative marriage, one which, though legally invalid, was contracted in good faith by at least one party." I hate when that happens!

The morphology of typing errors?

The title of the last post on this blog now reads "Sentence structure mistakes" but until a little while ago, it was "Sentences structures mistakes". That's a pretty striking case of something I see very often, in emails and in letters going back to the 19th c.: -s suffixes wandering or spreading around on words where they don't belong. This seems far more common than similar speech errors, though that's a mere hunch with not a speck of support. Is there work out there on this that I just don't know about?
