Introduction
When you wonder does their get capitalized in a title, you are tackling one of the most common points of confusion in English writing. Title capitalization rules dictate which words receive uppercase letters and which stay lowercase, and the answer depends on the specific word, its function in the title, and the style guide you follow. This article will break down the rules, explore the major style guides, and give you clear guidance on whether their should be capitalized when it appears in a title It's one of those things that adds up..
Understanding Title Capitalization
What Is Title Case?
Title case means that the first letter of each major word in a title is capitalized. The exact definition of “major word” varies by style guide, but it generally includes nouns, pronouns, verbs, adjectives, and adverbs. Articles, conjunctions, and prepositions are often left in lowercase unless they begin the title.
Major Style Guides
| Style Guide | Capitalization Rule for “their” | Notes |
|---|---|---|
| APA (American Psychological Association) | Lowercase their unless it is the first word or follows a conjunction/preposition of four letters or fewer | APA uses title case for headings, but only the first word and proper nouns are capitalized. Now, |
| MLA (Modern Language Association) | Lowercase their unless it is the first word or a proper noun | MLA follows a simpler rule: capitalize the first and last words, and all major words. |
| Chicago Manual of Style | Lowercase their unless it is the first word, a proper noun, or follows a short conjunction/preposition | Chicago is more flexible; many titles capitalize most words. |
| Title Case (General) | Capitalize their if it is a content word (noun, pronoun, verb, adjective, adverb) and not part of a short preposition or conjunction | The key is to treat their as a content word rather than a function word. |
From the table, it is clear that the capitalization of “their” hinges on its role in the title and the specific style guide you adopt. In most general title case conventions, their would be capitalized because it is a pronoun (a content word). Even so, if the title follows a strict sentence case or a style that leaves short prepositions and conjunctions lowercase, their may remain lowercase when it appears after such a word.
When to Capitalize “their” in a Title
Nouns vs. Pronouns
- Pronouns such as their, his, her, its, our, and your are considered content words. In most title case rules, they are capitalized unless they are part of a short prepositional phrase (e.g., “of”, “in”, “on”, “at”, “by”, “for”, “and”, “but”, “or”, “nor”).
- If their appears at the very beginning of the title, it is always capitalized regardless of style.
Position in the Title
- First Word – Capitalized in every style.
- After a Conjunction or Preposition –
- If the conjunction/preposition has four or fewer letters (e.g., “and”, “but”, “from”, “with”, “over”), many guides allow the following word to stay lowercase.
- If the conjunction/preposition has more than four letters (e.g., “between”, “through”, “against”), the following word is usually capitalized.
- Since their is a pronoun, it is typically capitalized after a short preposition, but you should check the specific style guide for exact rules.
Example Scenarios
- APA Style: “The report on their findings” → their remains lowercase because it follows the preposition “on”.
- Chicago Style: “Exploring their Impact on Society” → their is capitalized because it is a content word and not part of a short preposition.
- General Title Case: “The Story of their Journey” → their is capitalized, as it is a pronoun and the preposition “of” is short but the pronoun itself is a content word.
Common Mistakes
- Assuming All Words Are Capitalized – Not every word in a title is a “major” word. Articles (a, an, the), short prepositions, and coordinating conjunctions often stay lowercase.
- Over‑Capitalizing Small Words – Words like “of”, “in”, “on”, “and”, “but”, “or”, and “nor” should remain lowercase unless they begin the title.
- Ignoring Style Guide Specifics – APA, Chicago, and MLA each have subtle differences. Using the wrong guide can lead to inconsistent capitalization, which may affect the professionalism of your document.
FAQ
Q1: Does “their” need to be capitalized if it appears after the word “and”?
A: In most style guides, “and” is a coordinating conjunction that can be lowercase. If “their” follows “and”, it is generally capitalized because it is a content word, unless the specific guide dictates otherwise (e.g., APA may keep it lowercase if “and” is considered a short conjunction) Turns out it matters..
Q2: What if “their” is part of a hyphenated compound word?
A: Each element of a hyphenated compound is treated as a separate word. If “their” is the first element, it is capitalized; if it appears later, it follows the same rules as any other word in the compound Most people skip this — try not to..
Q3: Should I capitalize “their” in a subtitle?
A: Subtitles follow the same title case rules as the main title. If the subtitle is separated by a colon, the same capitalization applies to the words within the subtitle.
Q4: Does the presence of an apostrophe change capitalization?
A: No. The apostrophe does not affect capitalization. “Their’s” (the possessive form) would still be capitalized as “Their’s” if it appears in a title, following the same rules as “their”.
Q5: How do I decide which style guide to use?
A: Choose the style guide that matches the context of your work: academic papers often use APA, books and magazines may follow Chicago, and humanities essays typically use MLA. Consistency is key Turns out it matters..
Conclusion
The question does their get capitalized in a title does not have a single, universal answer; it depends on the word’s role, its position within the title, and the style guide you are following. Plus, in most general title case conventions, their is treated as a content word and therefore capitalized, unless it follows a short preposition or conjunction that the specific guide treats as a “lower‑case” element. In practice, by understanding the nuances of APA, Chicago, MLA, and general title case rules, you can confidently decide when to capitalize their and avoid common pitfalls that could undermine the professionalism of your writing. Remember to stay consistent throughout the entire document, and you’ll meet both grammatical correctness and reader expectations.
Practical Examples
Seeing the rules in action helps cement understanding. Below are several title snippets illustrating how “their” behaves under different style guides.
| Title (as it would appear) | Style Guide | Reasoning |
|---|---|---|
| Their Journey Through the Mountains | APA / Chicago / MLA | “Their” is the first word → always capitalized. In practice, |
| A Guide to Their Effective Communication | APA | “Their” follows the article “A” (not a short conjunction) → capitalized. |
| Strategies for Improving Their Performance | Chicago | “Their” follows the preposition “for” (treated as a short word) → lowercase in Chicago title case: “Strategies for improving their performance”. Also, |
| Balancing Work and Their Personal Life | MLA | “and” is a coordinating conjunction; MLA treats it as lowercase, so the following content word “Their” is capitalized: “Balancing Work and Their Personal Life”. |
| Exploring the Impact of Their’ (possessive) | Any | Apostrophe does not affect case → “Their’” stays capitalized if it appears as a content word. |
Quick Reference Chart
| Position of “their” | Capitalize? Because of that, (General Title Case) | APA | Chicago | MLA |
|---|---|---|---|---|
| First word | Yes | Yes | Yes | Yes |
| After a, an, the | Yes | Yes | Yes | Yes |
| After short preposition (in, on, of, to, for, with, at, by, from, up, down, out, over, under) | No (unless guide treats as content) | Yes (APA treats all major words) | No | No |
| After short conjunction (and, but, or, nor) | No (unless guide treats as content) | Yes | No | No |
| After long preposition/conjunction (because, although, however) | Yes | Yes | Yes | Yes |

Common Mistakes to Avoid
- Over‑capitalizing conjunctions – Treating every word as capitalized creates a “ALL‑CAPS” look that violates title case conventions.
- Ignoring hyphenation rules – Forgetting that each part of a hyphenated word is evaluated separately can lead to inconsistent styling (e.g., “Their‑Owned” vs. “their‑Owned”).
- Switching guides mid‑document – Mixing APA and Chicago rules in the same manuscript produces jarring shifts in capitalization that distract readers.
- Assuming apostrophes change case – The presence of an apostrophe does not alter whether a word should be capitalized; “their’s” follows the same rule as “their”.
- Neglecting subtitle punctuation – A colon or dash that separates title and subtitle does not reset capitalization rules; each segment must be evaluated independently.

Conclusion
Determining whether “their” appears capitalized in a title hinges on three interlocking factors: its grammatical role, its placement within the title string, and the specific conventions of the style guide you have adopted. While most major guides treat “their” as a content word worthy of capitalization, exceptions arise when it follows a short preposition or conjunction that the guide designates for lowercase treatment. By consulting the appropriate style manual, applying the quick‑reference chart, and adher
and adhere to the precise capitalization rules dictated by the style guide you are using. Even so, conversely, a Chicago‑styled title like “the Impact of Their on Energy” would lowercase “their” after the short preposition “of. Here's one way to look at it: an APA‑styled title such as “Their Impact on Renewable Energy” retains the capital “T” in “Their” because APA capitalizes all major words regardless of length. ” These examples show how the same term can be treated variably depending on the chosen manual and the word’s placement.
People argue about this. Here's where I land on it.
Thus, the decision to capitalize “their” rests on three considerations: its grammatical function, its position relative to short prepositions or conjunctions, and the specific conventions of the chosen style manual. By systematically applying the relevant rules and reviewing your title against the guide’s specifications, you can produce a title that is both compliant and polished. On the flip side, this disciplined approach eliminates ambiguity, supports consistency across your document, and reinforces the credibility of your work. Following these guidelines will make sure your titles meet the expectations of any academic or professional audience.
