The 11th edition of the venerable yet idiosyncratic Chambers Dictionary has just been published. Unlike the 11th editions of its lexicographical rivals Merriam-Webster's Collegiate and the Concise Oxford (everybody's going to 11 these days), the big news surrounding the latest Chambers is not about its new words. Rather, the British press has focused on some remarks made in the introduction to the dictionary, written by Newsnight presenter Jeremy Paxman. Paxman evidently likes to poke fun at all things Scottish, but he stepped over the line when he referred to the work of Robert Burns, Scotland's national poet, as nothing more than "sentimental doggerel."

Last time on Word Routes, we looked at a spelling error that's common enough to show up frequently in edited text: using acclimation when you mean acclamation. That's a case of battling homophones: the two words sound the same, but they have different meanings. The problem crops up with other sound-alikes, such as imminent vs. immanent, compliment vs. complement, principle vs. principal, and of course affect vs. effect. (We talked about that last pair recently in our interview with Jesse Sheidlower of the Oxford English Dictionary.) These mix-ups are particularly insidious because your spellchecker won't bail you out — unless, perhaps, you are using a contextual spellchecker like the one that has been developed for Microsoft Office.
