Is "By" Capitalized in a Title?

When you crack open a fresh style guide, such as Chicago, MLA, APA, or AP, you might find yourself in a world where every detail matters. One such detail is the capitalization of words in titles. You might wonder, for instance, if small words like 'by' deserve a big letter. This may seem like a minor thing, but it's crucial for polishing your writing to perfection. Each style guide has its own rules, and figuring out whether 'by' should be written with a capital 'B' in a title can feel like a puzzle. Stay tuned as we look into each of the style guides to reveal the mysteries of title capitalization!

Quick Answer

In Chicago, MLA, APA, and AP styles, the word "by" stays lowercase in a title unless it is the first word, the last word, or it directly follows a colon or dash. That rule is consistent across every major American style guide.

When you're writing a title, you might wonder if small words like 'by' should be in capital letters. It really depends on the style guide you're following. Let's go through a few to see when you should capitalize 'by'.

Chicago Manual of Style

According to the Chicago Manual of Style, you don't capitalize 'by' in a title unless it's the first or last word. This style favors lowercasing most prepositions, no matter their length.

Example: A Journey by Train

MLA Style

The MLA (Modern Language Association) style is similar to Chicago. You'll keep 'by' lowercase because it's a preposition, and MLA says prepositions with three or fewer letters should be in lowercase in a title unless they're the first or last word.

Example: Walking by the Lakeside

APA Style

APA (American Psychological Association) style asks you to capitalize words with four letters or more in a title. Since 'by' is only two letters long, you'll leave it lowercase.

Example: Guided by Stars

AP Style

The AP (Associated Press) style is different. This one says to capitalize the word 'by' only if it's part of a verb phrase. So if 'by' is used as a preposition, it stays in lowercase.

Example: Driven by Desire

in most major style guides, 'by' remains lowercase in a title unless it's the very first or very last word. Just make sure to check with the specific style guide you're using for your writing. Remember, staying consistent with your chosen style guide is key for professional and coherent writing.

When you create titles, remember that the word 'by' is usually not capitalized because it's a preposition with only two characters. Different style guides like APA, MLA, and Chicago agree on this rule. Small words like 'by' don't get a capital letter unless they're the first or last word in the title. Keep your titles clean and professional by following this simple guideline. This can make a big difference in the correctness of your writing.
