Understanding whether "should" requires capitalization within a title is essential for anyone crafting professional text. The specific rules governing this word depend entirely on its grammatical role and the style guide being followed. Generally, "should" is a modal verb, and modals are treated as lowercase in most title formats unless they appear as the first word.
The Basic Rule for Modal Verbs
In standard English writing, particularly in academic and journalistic contexts, short words such as auxiliaries are not capitalized mid-title. The word "should" functions specifically as a modal auxiliary verb, placing it in the same category as words like would, could, and might. Style manuals such as the Chicago Manual of Style and the Associated Press Stylebook explicitly state that such verbs should remain lowercase unless they are the first or last word of the title.
Exceptions to the Standard
While the default setting is lowercase, there are specific scenarios where capitalization is necessary. If "should" appears as the very first word of the title, it must be capitalized. Similarly, if it lands as the final word of the title, major style guides require it to be capitalized regardless of its part of speech. This ensures a consistent visual rhythm and adheres to the formal standards of publishing.
Title Case vs. Sentence Case
The treatment of "should" changes significantly depending on whether you are using Title Case or Sentence Case. In Title Case, which is common for headlines and publication titles, the word remains lowercase due to its status as a conjunction. Conversely, in Sentence Case, only the first word and proper nouns are capitalized, meaning "should" would typically be lowercase unless it begins the sentence. The context of the display medium dictates the appropriate choice between these two formats.
Use lowercase "should" in Title Case when it is not the first or last word.
Capitalize "Should" if it is the first word of the title or sentence.
In Sentence Case, follow standard sentence capitalization rules.
Treat the word as uppercase if it is the final word in the title.
Application in Digital Content
For digital content creators, the application of these rules impacts search engine optimization and user experience. Search engines tend to ignore capitalization for minor words when indexing keywords, so the visual formatting rarely affects SEO rankings. However, maintaining a professional appearance ensures credibility, and correctly writing "should" in titles signals attention to detail to the audience.
Practical Examples
To illustrate the grammar in practice, consider the difference between "What You Should Know About Grammar" and "Why You Should Update Your Resume." In the first example, "Should" is internal and follows the rule of lowercase for modals. In the second, it is the primary verb driving the action, making it permissible to remain lowercase as a minor word, though some styles might still capitalize it based on length.
The Role of Style Guides
Ultimately, the decision on whether to capitalize "should" rests on the specific style guide governing the document. Organizations like the Modern Language Association and the American Psychological Association have nuanced rules regarding length and word type. When in doubt, consulting the official manual or the style guide of the publication ensures that the title adheres to the expected linguistic standards.
