Title case rules
Title Case here follows the common AP/Chicago approach: capitalise the first and last word and all major words, and keep short articles, conjunctions and prepositions (a, an, the, and, but, or, for, nor, of, on, in, at, to, by, up, as, via) in lower case. Choose “Capitalize Each Word” if you want every word capitalised.
Frequently asked questions
Will this change acronyms such as NASA?
Title Case and Capitalize Each Word keep words that already contain capitals, such as NASA or iPhone (unless the whole text is in capitals). lowercase and sentence case lower every word, so check acronyms afterwards.
How do I make a URL slug?
Choose kebab-case. Punctuation is removed and words are joined with hyphens in lower case.
