When styling academic titles in APA format, writers often question whether common prepositions and short coordinating conjunctions should be capitalized. APA guidelines treat title capitalization as a blend of traditional title style and a clear set of rules designed for readability and consistency.
This article explains how to handle capitalization in APA titles, focusing on when to capitalize words like "is" and other frequently debated terms. The following references and style principles align with the latest APA formatting expectations.
| Element | APA Title Capitalization Rule | Example with "Is" | Display in Reference List |
|---|---|---|---|
| First word of title | Always capitalize | Is | Bold primary word |
| Nouns, pronouns, verbs | Capitalize | Is | Retains capitalization |
| Articles, short prepositions, coordinating conjunctions | Lowercase unless first word | is | Lowercase in body |
| Words after colon | Capitalize first word | Is | Consistent with colon rule |
Capitalizing Is in APA Headings and Titles
APA style treats headings and titles with a balanced approach that supports clarity. In a title, the word "is" functions as a verb and is therefore capitalized, while in the reference list it follows the same rules as other short words in the title.
Headings within papers use five levels, and the capitalization pattern in each level mirrors the rules for titles. This consistency ensures that readers can distinguish section hierarchies without confusion, regardless of whether "is" appears at the start or in the middle of the line.
For students and researchers, applying these rules consistently across headings, figure titles, and table headings reduces revision cycles and aligns manuscripts more closely with publisher expectations.
Reference List Title Capitalization Details
In the reference list, APA style uses sentence case for book and article titles, which means only the first word of the title and subtitle, as well as proper nouns, are capitalized. Because "is" is usually not the first word, it appears in lowercase unless it is a noun or pronoun in specific contexts.
Journal titles are typically italicized and follow sentence case as well, while major words within the journal title itself may be capitalized depending on the source. This disciplined formatting supports readability and helps automated systems parse references accurately.
When titles include colons, the word immediately following the colon is capitalized, which can affect how "is" is displayed if it appears after this punctuation mark.
Practical Application in Academic Writing
Applying APA capitalization rules in practice requires attention to both headings and cited titles. Writers should use automated tools cautiously and always verify edge cases manually to avoid formatting errors.
Consistent capitalization in titles and headings enhances the professionalism of a manuscript and signals attention to detail. Researchers who align their work with APA standards demonstrate respect for editorial review processes and increase the likelihood of smoother publication workflows.
Style guides and institutional templates often provide examples that help writers translate general rules into specific formatting decisions across different disciplines.
Common Mistakes and How to Avoid Them
Misapplying headline-style capitalization to APA references is a frequent issue, especially for early career researchers. Another pitfall is inconsistent treatment of "is" across similar documents, which can undermine the perceived rigor of a paper.
Using built-in heading styles and reference managers reduces manual formatting work and minimizes deviations from APA guidelines. Maintaining a personal checklist of recurring issues, such as capitalization after colons or handling of compound titles, further supports accuracy.
Final Practice Recommendations for APA Title Capitalization
- Capitalize verbs such as "Is" in titles and headings across all APA levels.
- Use sentence case in reference list entries, keeping "is" lowercase unless it starts the title.
- Apply consistent rules after colons to maintain predictable formatting.
- Leverage style tools while periodically reviewing manual examples for accuracy.
- Align heading hierarchy with publication requirements to streamline review and revision.
FAQ
Reader questions
Should I capitalize "is" in an APA style title?
Yes, capitalize "Is" in titles and headings because it is a verb, which APA style requires to be capitalized regardless of length.
How should "is" appear in a reference list entry?
Use sentence case, so "is" remains lowercase unless it is the first word of the title or subtitle.
Does the treatment of "is" change in level one headings? Level one headings capitalize major words, so "Is" is capitalized when it functions as a verb or noun within the heading. What happens to "is" after a colon in an APA title?
Capitalize the first word after a colon, which means "Is" would be capitalized if it follows the colon.
