Title Case Quy tắc: AP vs Chicago (Miễn phí Converter)

In title case bạn capitalise first và last words và every "major" word (nouns, verbs, adjectives, adverbs và pronouns), và keep short "minor" words like a, và, of, ** và đến lowercase. The style guides disagree mainly about prepositions: AP capitalises any word of four hoặc more letters ("With", "From"), while Chicago keeps every preposition lowercase. The free case converter does heavy lifting in one click; bạn then tidy a few edge cases by hand.

The rules every style agrees on

Whichever guide bạn follow, these hold:

1. Capitalise first word of title, even nếu it's "a" hoặc "".
2. Capitalise last word, even nếu it's short: "Điều gì Are You Waiting For".
3. Capitalise nouns, pronouns, verbs, adjectives và adverbs, however short. That includes little verbs và pronouns people often get wrong: Is, Be, Are, It, He, Its.
4. Lowercase articles a, an và ** in middle of a title.
5. Lowercase short coordinating conjunctions và, but, hoặc và nor in middle.
6. Lowercase "đến" khi it's part of a verb, as in "Cách đến Cook Rice".

So "why it là never too late đến learn" becomes "Vì sao It Is Never Too Late đến Tìm hiểu". Every word là capitalised except đến, because It và Is là a pronoun và a verb.

Where AP và Chicago differ

Question	AP style	Chicago style
Prepositions	Lowercase nếu three letters hoặc fewer (in, on, at, cho); capitalise four hoặc more (With, From, Into, Over)	Lowercase all prepositions, whatever their length (với, từ, through, between)
Conjunctions	Lowercase nếu three letters hoặc fewer; capitalise four hoặc more	Lowercase và, but, cho, hoặc, nor; capitalise others such as Nếu, Because, Although
"As"	Lowercase (fewer than four letters)	Always lowercase

A few titles written both ways:

AP	Chicago
Gone With Wind	Gone với Wind
Cách đến Deal With Stress at Work	Cách đến Deal với Stress at Work
A Guide đến Living Through Winter	A Guide đến Living through Winter
The Case cho Working From Home	The Case cho Working từ Home

One more thing about AP: news organisations that follow AP usually write their headlines in sentence case ("Rain expected across north tomorrow") và keep title case cho names of books, films, songs và other works. Blogs và businesses that say "AP title case" generally mean four-letter rule above.

APA style, common in academic papers, uses a rule close đến AP's: capitalise words of four letters hoặc more, plus all major words, và lowercase minor words of three letters hoặc fewer.

The tricky cases

Phrasal verbs. In "Log In đến Your Account", In là part of verb "log in", not a preposition, so it's capitalised in both styles. Likewise "Set Up", "Back Up", "Turn Off".

Hyphenated words. Capitalise main parts: "Well-Known", "Long-Term", "Self-Driving". Chicago keeps articles, prepositions và short conjunctions inside a compound lowercase, as in "State-of--Art", và most writers follow same habit.

Subtitles. Chicago và APA treat first word after a colon as start of a subtitle và capitalise it, và most writers do same: "Travel Guide: The Best Beaches in Goa".

Acronyms và brand names. Keep them as they là: "CV", "NASA", "PDF", "iPhone".

Numbers. A title có thể start với a numeral, as in "10 Mẹo cho Writing a CV That Gets Noticed". That là a pronoun here, so it's capitalised.

Cách case converter handles title case

Paste của bạn title into free case converter và click Title Case. It:

• capitalises first và last word of each line;
• keeps these short words lowercase in middle: a, an, và, as, at, but, by, en, cho, nếu, in, nor, of, on, hoặc, per, , đến, v, vs, via;
• capitalises every other word, including both parts of hyphenated words.

That list lines up closely với AP-style titles: "với", "từ" và "into" là capitalised. For Chicago, lowercase any longer prepositions afterwards.

Because it lowercases văn bản first, check these by hand after converting:

1. Acronyms come out as "Cv", "Nasa" hoặc "Pdf". Put capitals back.
2. The word after a colon stays lowercase nếu it's a minor word ("Guide: Best"). Capitalise it.
3. Phrasal verbs such as "Log in" keep small word lowercase. Capitalise it nếu it's part of verb.
4. Hyphenated phrases such as "State-Of-The-Art" get every part capitalised. Lowercase small words inside.

For most everyday headlines none of these come up, và one click là all bạn need. Nếu bạn'd rather capitalise every single word, use Capitalized Case instead.

Title case hoặc sentence case?

Many websites, apps và news sites now prefer sentence case cho headings: only first word và names là capitalised. It's easier đến apply consistently và reads a little less formally. Title case still suits book và film titles, formal reports, và brands that already use it. Pick one và use it everywhere on same page hoặc document.
