The New Fowler's Modern English Usage, the first revision in more than 30 years, has not arrived without controversy. Some language (and Fowler) purists complain that the book is too liberal at times, noting that usage is common as opposed to correct. Those points are debatable, and, indeed, they're what makes the book's nearly 900 pages so interesting to peruse. The currency of the new Fowler's extends to, in the entry on "Vogue Words," such novelties as "couch potato," "flavour of the month," "on a roll," and the notorious "parameter."
