AP Style Update: Style and Grammar Basics

AP Stylebook

[Editor’s Note: One of the most popular articles on prnewsonline.com is a review and summary of AP style. We took that as a sign and decided to deliver a series of AP style updates for newsworthy topics. Previously, the series looked at terms for writing about cryptocurrency and diversity, equity and inclusion (DEI) and finance, among other topics.]

For this installment, we explore grammar basics of AP style that writers use on a daily basis. 

occupational titles: 

Only capitalize formal titles used before an individual’s name. Titles that serve as occupations should be lowercase. Also lowercase titles when they are not used with an individual’s name.

The baseball team went to visit President Joe Biden at the White House.

The dentist, Joe Smith, spoke to the council of doctors.


composition titles: 

These guidelines apply to titles of books, movies, plays, poems, albums, songs, operas, radio and television programs, lectures, speeches, and works of art:

  • Capitalize all words in a title except articles (a, an, the); prepositions of three or fewer letters (for, of, on, up, etc.); and conjunctions of three or fewer letters (and, but, for, nor, or, so, yet, etc.)
  • Put quotation marks around titles (“The Star-Spangled Banner,” “Star Wars,” “Game of Thrones,” “To Kill a Mockingbird”) except the Bible, the Quran and other holy books, and books that are primarily catalogs of reference material (almanacs, encyclopedias, etc.) 
  • Do not use quotation marks around software titles (WordPerfect, Windows), apps, video games or board games (Super Mario Brothers, Uber, Monopoly)


I’ve never seen “Star Wars,” but I’m excited to watch it. 

My friends host a Guitar Hero competition every year.


state abbreviations/U.S.:

Always spell state names whether on their own or in conjunction with a city, town, village, etc. The only time a state is abbreviated is when used in a dateline. Eight states are never abbreviated (Alaska, Hawaii, Idaho, Iowa, Maine, Ohio, Texas and Utah). Always spell United States on first reference, and use U.S.on second reference.

Use a two-letter postal code abbreviation only with a full address that includes zip code.

Do not abbreviate states in headlines or titles.

These are times when it is acceptable to use abbreviation: 

  • Lists
  • Tables
  • Datelines
  • Photo captions
  • Political party affiliation
