Decades ago, in college, we were all required to buy Fowler’s Modern English Usage, originally published by H.G. Fowler but then in a 2d revised edition by Sir Ernest Gowers. It was brilliant, and it didn’t always make sense to my ears because — well, because I am an American. And my idea of “modern” wasn’t quite the same as old HG’s or Sir Ernest’s.
So I was elated to discover Garner’s Modern American Usage, by Bryan Garner, published by Oxford University. (Shown is the 3d edition, 2009). It’s modern. It’s American. And it’s just what every writer needs. It even includes a “language-change index” which does exactly what it says.
I am certain HG and Sir E would approve.
