Different Style Guide Options, Same Rules
You may have heard about different style guide and reference list options; however, the rules are generally the same. Numerous major organizations, including the American Psychological Association, the Associated Press, and even the New York Times have released a publication manual.
No matter what capitalization style you follow, whether this is APA Style, AP Style, or MLA Style, the rules will be similar. You should use title case capitalization for titles, headings, subtitles, and subheadings. You should use sentence case capitalization for everything else.
Comparing Sentence Case and Title Case
It may be helpful to compare the rules of sentence case and title case. In sentence case, the vast majority of major words and minor words are lowercase. Major words include adjectives, adverbs, pronouns, nouns, verbs, and proper nouns. Minor words include short prepositions, subordinating conjunctions, coordinating conjunctions, and articles.
You should use capital letters for:
- The first word after end punctuation such as periods, exclamation marks, and question marks
- Proper nouns, including the names of ethnic groups
- The first letter of the first word of titles, headings, subheadings, and subtitles
You should use lower case letters for everything else.
If you are following title case, the rules change it slightly. You should capitalize:
- The first letter of all major words
- All words that are longer than three letters, even if they are minor words
- The first letter following end punctuation
- Both words, if they are part of a hyphenated compound
- The first letter of the first word following a colon or em dash
