|It's "off-season" on pg. 183...|
|... but it's "offseason" 115 pages later.|
So, imagine my surprise when, years ago, I found an error in the edition published in 2002. On page 183, in the "off-, -off" entry, the stylebook lists "some commonly used combinations with a hyphen," including off-season. Flip ahead to the Sports Guidelines on page 298, however, and you'll notice the following entry: "offseason (no hyphen)."
That error is the source of continuous, er, continual amusement.
