When drafting titles for articles, essays, or web pages, the question of whether to capitalize "is" often creates uncertainty. Style guides vary, and the standard rules of grammar do not always provide a clear answer for short verbs and linking words. Understanding the principles behind title capitalization allows you to make confident decisions that ensure your writing appears professional and polished across different contexts.
The Rules of Title Capitalization
Most style guides, including APA, MLA, and Chicago, recommend capitalizing the major words in a title. This typically includes nouns, verbs, adjectives, adverbs, and pronouns. However, articles, coordinating conjunctions, and prepositions are generally lowercased unless they appear at the beginning or end of the title. The word "is" functions as a linking verb, which places it in a gray area where specific formatting choices come into play depending on style preferences and length.
When to Capitalize "Is"
You should capitalize "Is" when it is the first or last word of the title. Maintaining capitalization at the boundaries ensures the title looks balanced and adheres to standard formatting. Additionally, some style guides suggest capitalizing verbs of all lengths to preserve the visual rhythm of the title, especially if the title is short or "is" serves as a primary verb driving the statement.
Capitalize at the start: Is Running Worth the Risk?
Capitalize at the end: The Strategy to Win Is
Capitalize when following a colon: Planning: Is It Enough?
When to Keep It Lowercase
In longer titles, keeping "is" lowercase often creates a cleaner and more readable appearance. Since short prepositions and conjunctions are traditionally lowercased, treating "is" as a brief linking word aligns with conventions that prioritize clarity. If the title contains multiple short words, capitalizing every element can look cluttered, so discretion is necessary to maintain a professional look.
Context and Consistency Matter
Beyond rigid rules, the context in which the title appears plays a significant role. Academic writing often follows strict style manuals, while marketing content may prioritize visual flow and readability. Regardless of the medium, maintaining consistency across all titles ensures your work looks cohesive and authoritative. Readers subconsciously notice uniformity, and varying treatment of the same word can distract from your core message.
Search engines also consider title formatting when displaying snippets, so choosing a clear and structured approach improves visibility. A title that confidently handles small words like "is" signals attention to detail. By reviewing established guidelines and aligning with the expectations of your audience, you can handle capitalization with precision and produce titles that are both grammatically sound and visually compelling.
