So enjoy it while it lasts, Community of Concern. Mr. Rewrite is blogging again. He usually flames out after several months.
Today's discovery: The AP Stylebook calls for pregame rather than pre-game. It's the same story with postgame. You'll find it in entries on postgame, pregame and pre-.
Pregame is consistent with AP's rules for prefixes in general: Go with a hyphen only when the last vowel of the prefix is the same as the first of what comes after (e.g. pre-election).
What's funny about this discovery is AP's sports folks don't seem to follow the stylebook well on this point. Follow this link to many, many uses of pre-game in AP stories.
The moral: Do as AP says, not as AP does.
