Please note that this guide is based on the AP Stylebook, last updated June 1, 2022.
This guide does not include everything contained in the stylebook. Rather, it aims to cover the most salient points and provide details of AP Style’s approach to key editorial issues.
The following should be used as additional authorities to AP Style:
Webster’s New World College Dictionary (use the first spelling listed unless AP Style specifies otherwise).
New York Stock Exchange, Nasdaq or the Securities and Exchange Commission for formal company names. Use Co., Inc., Ltd., Corp. after the name as appropriate.
National Geographic Atlas of the World for place names not in Webster’s.
It wouldn’t be practical to list all the punctuation rules here. Instead, we’ve included those AP Style punctuation rules that might go against common practice.
Note that AP Style values consistency, so you can often determine what to do in a given situation by following related rules.
Otherwise, use standard U.S. English practice unless the client has requested another dialect.
See also Quotations in the Style section of this guide.
AP Style doesn’t say much about references/citations. The following are some notes about the mention of creative works in text.
See also Third-party Sources in the Style section of this guide.
Here are some (perhaps) non-standard approaches to spelling, capitalization and form found in AP Style. Only those that differ from Webster’s Dictionary (or do not clearly appear in it) are included here.
(If we’ve missed any out, please let us know!)
Tip: To confirm whether the first word in a Webster’s entry is capitalized, scroll down to look at the “other word forms” in the dictionary entry.
Here is a list of terms for which AP Style has stated a preference. Note that:
