No. "At" is a two-letter preposition, and all six major style guides keep it lowercase in the middle of a title. It is one of the few words where AP, APA, Chicago, MLA, AMA, and Bluebook agree completely.
"At" by Style Guide
| Style guide | "At" mid-title | Why |
|---|---|---|
| AP | Lowercase | Prepositions of three or fewer letters stay lowercase |
| APA | Lowercase | Short prepositions (three or fewer letters) stay lowercase |
| Chicago | Lowercase | Prepositions are lowercase at any length |
| MLA | Lowercase | Prepositions are lowercase at any length |
| AMA | Lowercase | Prepositions of three or fewer letters stay lowercase |
| Bluebook | Lowercase | Prepositions of four or fewer letters stay lowercase |
Examples in Chicago Style
- A Night at the Museum
- Breakfast at the Diner on Main Street
- Why We Work at Home
- Dinner at Eight
Each of those headlines comes out the same in AP, APA, Chicago, and MLA, because the only small words in them are articles and short prepositions.
When "At" Is Capitalized
- First word: "At Home With the Garden" (AP style) or "At Home with the Garden" (Chicago).
- Last word: AP, Chicago, and MLA capitalize the final word, so "Where It's At" ends with a capital. APA has no last-word rule, so it keeps a short final preposition lowercase.
- First word of a subtitle: "Remote Work: At Home and Abroad" capitalizes "At" after the colon.
Mixing Up "At" and "It"
"At" and "it" look alike but follow different rules. "It" is a pronoun, so every guide capitalizes it: "Make It Work" versus "Meet at Noon." Other two-letter words depend on their job in the title. "As" is the trickiest, because the guides treat it differently when it works as a conjunction.
Real Titles With "At"
- Night at the Museum (2006 film)
- Breakfast at Tiffany's (Truman Capote)
- Midnight at the Well of Souls (Jack L. Chalker)
All three keep "at" lowercase mid-title, which matches every major guide.
"At" in Sentence Case
APA reference lists, many news sites, and most UI text use sentence case instead of title case. There, only the first word and proper nouns get capitals, so "at" is lowercase unless it starts the title: "A night at the museum." Pick one of the two styles for a whole set of headings rather than mixing them.
