Ap Title Case フォーマットに関するよくある質問
AP title case is the headline capitalization style defined by the Associated Press Stylebook. It capitalizes principal words and all words of four or more letters, while lowercasing short articles, conjunctions, and prepositions (three letters or fewer) unless they are the first or last word.

AP capitalizes words of four or more letters and all verbs. Chicago traditionally lowercases all prepositions regardless of length.
