What is Title Case Capitalization?
Title case is the standard capitalization convention used for headlines of news articles, book titles, magazine features, and academic dissertations.
In title case, the first and last words of the headline are always capitalized. Major content words (nouns, pronouns, verbs, adjectives, adverbs) are also capitalized, while minor function words (articles, coordinating conjunctions, and short prepositions) remain in lowercase unless they begin the sentence or follow a colon.
