AP style changes
Doug Fisher, at Common Sense Journalism, has a recap of what's new in the 2005 AP Stylebook. Read his whole entry, but here's a few I haven't talked about much:
backyard: Now one word in all uses, noun and adjective.
child care: Use as two words in all instances, including as an adjective. (But no mention of day care.)
physician assistant: Not physician's.
sync: Short for synchronization, not synch.
voice mail: Two words.
