Writers and researchers often encounter specific formatting challenges when preparing manuscripts for academic publication, particularly regarding capitalization rules. The question of whether to capitalize "is" in a title following APA Style guidelines represents a common point of confusion. Understanding the mechanics of title case according to the official Publication Manual ensures that your work appears polished and adheres to scholarly standards, avoiding unnecessary revisions during the submission process.
APA Title Case Fundamentals
The core principle of APA Style title case is to capitalize major words to create a clear and visually distinct heading. This includes nouns, pronouns, verbs, adjectives, and adverbs, which form the substantive elements of your phrase. Conjunctions, articles, and short prepositions are generally left in lowercase unless they meet specific criteria, such as being the first or last word of the title. This selective capitalization guides the reader's eye and maintains a professional aesthetic across academic journals.
The Specific Status of "Is"
To address the central query directly, the word "is" functions as a verb, specifically a linking verb or a form of the verb "to be." Because verbs are considered major words in the APA framework, "is" must be capitalized when it appears in the title of your paper, regardless of its length or position. Whether you are writing "The Data Is Valid" or "How Success Is Achieved," the verb "is" receives capital lettering as a standard rule of grammar within the style guide.
Exceptions and Nuanced Application
While the verb "is" is generally capitalized, context matters when dealing with title case. If "is" appears as part of a hyphenated compound word, the standard title case rules for compounds apply, which usually dictate capitalizing only the first element unless the second element is a proper noun. Furthermore, the formatting of references list titles follows the same logic, ensuring consistency between the main text and the documentation of sources.
Capitalize "is" when it serves as the main verb linking the subject to a complement.
Keep "is" lowercase only if it were an article or a conjunction, but it is not.
Treat "is" with the same weight as other action or state verbs like "runs" or "seems".
Verify the style guide if you are formatting a specific section like the abstract, though the rules remain consistent.
Practical Implementation in Headings
Applying these rules to actual document structure requires attention to the hierarchy of headings. Level 1 and Level 2 headings should follow the same title case conventions as the title of the paper itself. Therefore, a heading such as "Data Analysis Is Crucial" would correctly capitalize the "is" to maintain grammatical accuracy and visual harmony with the rest of the document. This practice reinforces the professionalism of the text.
Distinguishing Title Case from Sentence Case
It is essential to differentiate APA title case from sentence case, which is sometimes used for abstracts or references. In sentence case, you only capitalize the first word of the title, the first word of a subtitle, and any proper nouns. Under the title case standard, however, the word "is" is always treated as a capitalizable element. Confusing these two formats results in inconsistent formatting that detracts from the rigor expected in academic writing.
Verification and Final Checks
To ensure accuracy, reviewing the specific examples in the official APA manual or using a reliable title case generator can be helpful. These tools confirm that verbs like "is," "are," and "was" are appropriately capitalized in headings and titles. Mastering this detail demonstrates a command of the technical aspects of scholarly writing, allowing the quality of your research to be the primary focus of the review process.
