When drafting a headline or editing a colleague’s work, you likely pause at the question of whether the word is capitalized in a title. The answer hinges on a set of established style rules combined with the specific word’s grammatical role. Understanding these nuances transforms a patchwork of guesswork into a precise, professional standard that elevates the credibility of any document.
The Core Principle of Title Capitalization
Most style guides, including APA, Chicago, and AP, agree on a fundamental framework for capitalization. The primary rule is to capitalize the first and last words of the title, regardless of their part of speech. This foundational step ensures the headline has a clear starting point and a strong visual anchor for the reader.
Capitalizing Nouns, Verbs, and Adjectives
Beyond the first word, the standard practice is to capitalize major words. This category includes nouns, verbs, adjectives, adverbs, and pronouns. If the word in question functions as one of these elements, it is typically capitalized. For instance, in the phrase "the Impact of Change," "Impact" is capitalized because it is a noun conveying the core subject of the sentence, even if it is a short word.
Lowercasing Articles, Conjunctions, and Prepositions
Conversely, there are specific word types that are usually left lowercase unless they are the first or last word of the title. These include articles (a, an, the), coordinating conjunctions (and, but, or, nor, for, so, yet), and short prepositions (in, on, at, to). If the word you are questioning is one of these functional elements, the conventional answer is generally no, it is not capitalized.
Addressing the Specific Word "Is"
This brings us directly to the specific case of the word "is." The question of is the word is capitalized in a title requires looking at its grammatical classification. "Is" is a form of the verb "to be," which places it firmly in the category of a verb. According to the rules outlined above, verbs are major words that should be capitalized.
Therefore, in nearly all standard title formats, "Is" is capitalized. You would write "The Cat Is Sleeping" rather than "The Cat is Sleeping." There is one notable exception to this guideline: if you are following Associated Press (AP) style specifically for journalism, some publications lower all verbs shorter than five letters. However, the predominant standard in academic and corporate writing is to capitalize "Is" to maintain a polished and authoritative tone.
Practical Application and Consistency
While the rules provide a clear map, the true test lies in consistent application. When crafting a title, it is best to evaluate every word against the same criteria. This prevents awkward inconsistencies, such as capitalizing "and" while leaving "the" lowercase. Tools like title capitalization converters can be useful for verification, but developing an internal sense for these guidelines ensures faster, more confident editing.
