A man who works in Olympia had this question:

"I've often wondered why a corporation based in Washington has a spell-checker that doesn't include Walla Walla as an acceptable proper noun instead of insisting that it's a repetition... Apparently, Microsoft thinks there's a town called Walla, WA -- where they grow Walla onions." (Only half as delicious, I'm sure.)

And for anyone who wants to see the original version of Jerrold Zar's "Candidate for a Pullet Surprise," here's a link (PDF). The poem begins:

I have a spelling checker,

It came with my PC.
It plane lee marks four my revue
Miss steaks aye can knot sea.

What words wood ewe like to sea added to the spell checker? Or, what are your favorite examples of the Cupertino effect -- odd "corrections" or errors introduced by spell checkers?

Update, 11:54 a.m.: Mike Calcagno just passed on this update about the word "borehole." "I am pleased to report that the word 'borehole' is verified in Office 2007."

Likewise, a commenter noted that "Walla Walla" is recognized in Office 2007.

I first thought to write about this team after reading a question posed to New York Times technology writer David Pogue about the Obama-Osama issue earlier this month. The issue continues to surface even though the team sent out a fix for the issue in spring 2007.

All three of these are examples of what winds up being a tough problem for Calcagno and team: Even as they regularly make progress, adding thousands of words to each new speller, the effort is lost on people who have old versions of Word.

Updated, 12:45 p.m.: Oh, this one is embarrassing. But I'd rather you read it here first than on Regret The Error later.

Brenda Flynn wrote asking me to settle a "hot debate" among her friends sparked by today's story, in which I mention the name of popular dictionary publisher.

"The dictionary-maker's name is Merriam-Webster, with two 'rs'," Flynn wrote. "Votes among my friends are running slightly ahead for 'cleverly ironic misspelling'. Was it subtle irony intended for the lexocographally-inclined [sic], or was it an honest proper name mistake?"

Her friends are too kind. I wish I could say I intentionally introduced the error and our copy editors conspired with me. Alas, no. Maybe we can pretend?

Look for our correction online and in tomorrow's paper.
