1The Core Rule
Capitalise nouns, verbs, adjectives, and adverbs. Do NOT capitalise articles (a, an, the), short prepositions (in, of, at), or coordinating conjunctions (and, but, or) — unless they are the first or last word.
2Style Guide Differences
APA, Chicago, and AP style have slightly different rules. Chicago is the most commonly used for publishing.
