The rules of title case can be complex, with various exceptions and nuances to consider. In general, title case refers to the practice of capitalizing the first letter of each major word in a title or heading, while leaving minor words such as articles and prepositions in lowercase. However, there are several exceptions to this rule that can affect how titles are formatted.
Proper Nouns and Title Case

One of the primary exceptions to title case involves proper nouns, which should always be capitalized regardless of their position in the title. This includes names of people, places, organizations, and specific events. For example, in the title “The History of Microsoft,” the proper noun “Microsoft” is capitalized, while the article “The” and the common noun “History” are also capitalized due to their position in the title.
Minor Words in Title Case
Minor words, such as articles (“the,” “a,” “an”), conjunctions (“and,” “but”), and prepositions (“in,” “on,” “at”), are typically not capitalized in title case unless they are the first or last word of the title. This rule helps to distinguish between major and minor words, emphasizing the importance of the major words in the title. For instance, in the title “The Effect of Climate Change on Global Temperatures,” the minor words “of” and “on” are in lowercase, while the major words are capitalized.
Word Type | Capitalization Rule |
---|---|
Proper Nouns | Always capitalize |
Major Words | Capitalize unless minor word |
Minor Words | Do not capitalize unless first or last word |

Hyphenated Compounds and Title Case

Hyphenated compounds present another exception in title case. When a hyphenated compound is used in a title, both words should be capitalized. For example, in the title “The Self-Driving Car Revolution,” both “Self” and “Driving” are capitalized due to the hyphenation. This rule ensures that the entire compound is emphasized as a single unit, even though it consists of two separate words.
Numbers and Title Case
Numbers in titles can also be subject to specific capitalization rules. When a number is part of a title, it is often capitalized if it is a major word or part of a proper noun. For instance, “The 7 Wonders of the Ancient World” capitalizes the number “7” because it is integral to the title’s meaning. However, the treatment of numbers can vary depending on the style guide being followed.
Key Points
- Proper nouns are always capitalized in title case.

By understanding and applying these rules, individuals can ensure that their titles are not only grammatically correct but also visually appealing and consistent, thereby enhancing the overall quality of their written work.
