How Title Casing Works
Title casing is more complex than simply "capitalizing every word." Our algorithm distinguishes between "major" and "minor" words based on linguistic rules.
Major words—including nouns, pronouns, verbs, adjectives, and adverbs—are always capitalized. Minor words, such as short prepositions (to, in, on), coordinating conjunctions (and, but, for), and articles (a, an, the), remain lowercase unless they are the first or last word of the title. Our tool also handles hyphenated terms like "Full-Time" and preserves the original casing of technical acronyms like "NASA" or "HTML."
Practical Input → Output Examples
1. Standard Web Headline
Input: "the quick brown fox jumps over the lazy dog"
Output: "The Quick Brown Fox Jumps Over the Lazy Dog"
Corrects capitalization while keeping minor words like 'the' and 'over' lowercase.
2. AP Style Consistency
Input: "how to build a website in 10 minutes"
Output: "How to Build a Website in 10 Minutes"
Follows Associated Press rules for short word exclusions and starting/ending words.
3. Hyphenated & Technical Terms
Input: "a guide to low-cost nasa initiatives"
Output: "A Guide to Low-Cost NASA Initiatives"
Correctly handles compound adjectives and preserves technical acronyms.
Common Mistakes & Misunderstandings
Capitalizing Every Preposition: A frequent error is capitalizing all prepositions. While long prepositions (like 'Between') are capitalized in some styles, short ones should almost always be lowercase.
Acronym Formatting: Many automated tools convert "NASA" to "Nasa." Use our 'Preserve Acronyms' toggle to ensure technical and organizational names stay in their correct format.
Punctuation Rules: Many writers forget that the first word after a colon (:) or em-dash (—) in a title should be capitalized, even if it is a short "minor" word.
What’s the difference between Standard and AP style?
Standard keeps common short words lowercase except at the start or end. AP style follows newsroom rules for articles, conjunctions, and short prepositions.
Do acronyms stay uppercase?
Yes, when acronym preservation is enabled, words in ALL CAPS remain unchanged.
How are hyphenated words handled?
Each part is capitalized unless it’s a short minor word in the middle, depending on the selected mode.
Will punctuation affect capitalization?
Words after sentence or clause punctuation like colon or em dash are treated as starts and capitalized.
