Daniel Cassidy’s “How the Irish Invented Slang” was recently the subject of a flattering (some might say fawning) story in The New York Times.

Grant Barrett, professional lexicographer and the editor of The Official Dictionary of Unofficial English, called bullshit on Cassidy in a post on his blog and here on Wordie. Our own beloved sionnach weighs in as well.

It’s not exactly bareknuckles–this is Wordie, we try to be civilized–but it’s edifying to hear from the pros about what constitutes proper lexicography. I’d like to hear Cassidy’s response (Barrett isn’t the only one to find fault), but as far as I can tell he hasn’t responded to his critics, on Wordie or anywhere else.
