Lowercasing a proper name can change meaning, make writing look careless, or confuse readers. Use the short rules and copy-paste corrections below to spot errors and fix sentences quickly.
If a name looks wrong in context, test the whole sentence: context often makes the correct casing obvious.
Quick fix
Capitalize the first letter of any proper name-people, places, organizations, products, events and official course or job titles when used as part of a name. Keep generic nouns lowercase unless they form part of an official title; follow a brand's preferred casing when precision matters.
- People and family names: Maria, Smith-Jones.
- Places and geographic features: Mount Rainier, Paris.
- Organizations and products: Acme Corp., iPhone (use brand case when required).
- Titles: capitalize when used before a name (Mayor Lopez); lowercase when generic (the mayor).
- Possessives and punctuation: keep the name capitalized with apostrophes or prefixes (Harry's, O'Neill).
Core explanation: what counts as a proper name
A proper name identifies a single, named entity: a person, organization, place, product, event or titled work. Capitalize names that refer to that unique entity in context.
- Official names: capitalize (University of Toronto, Nike).
- Generic uses: keep lowercase (the university, the company) unless the phrase is the official title.
- When a brand or institution stylizes its name unusually (e.g., lowercase), prefer that styling in quotations or branded contexts; follow your style guide elsewhere.
- Example - people vs. generic: wrong → right: dr. chen → Dr. Chen; the doctor → the doctor.
- Example - institutions: wrong → right: university of michigan → University of Michigan; the university → the university.
Grammar rules checklist (quick scan)
Run these checks in order. If any answer is yes, capitalize the word or phrase.
- Is it the official name of a person, place, organization, product or event? → Capitalize.
- Is it a formal title used immediately before a name? → Capitalize that title.
- Is it a generic noun describing a type (department, university, company) without an official name attached? → Lowercase.
- Does a brand or product use special casing (e.g., iPad, eBay)? → Match the brand when precision matters.
- Check examples: wrong → right: marketing department → Marketing Department (only if the org uses that as a proper name) vs. the marketing department (generic).
- Check examples: wrong → right: apple released an update → Apple released an update; use iPhone for the product name.

Try your own sentence
Test the full sentence rather than an isolated word-surrounding words often clarify whether a name is proper.
Hyphenation and spacing: hyphenated names, particles and apostrophes
Follow the individual's or institution's preferred spelling. When unsure, capitalize the main elements and the letter after punctuation where convention requires it.
- Hyphenated surnames: capitalize both parts (Smith-Jones).
- Apostrophes and O- prefixes: capitalize the conventional form (O'Neill, D'Angelo).
- Name particles (de, van, la): usage varies-follow the person's styling; if unknown, capitalize the principal surname according to local convention (De la Cruz or de la Cruz).
- smith-jones → Smith-Jones
- o'connor → O'Connor
- de la cruz → De la Cruz (or de la Cruz-use the person's preference)

Memory trick: three fast checks to catch lowercase names
Use these quick mental tests when scanning text.
- Ask: Is this a unique, named entity? If yes, capitalize.
- If a job title appears immediately before a name, capitalize the title.
- If unsure about a brand or course title, copy the casing from the official source.
- Mnemonic: Replace the word with "Company" or "Person." If the sentence still points to a specific entity, capitalize the original.

FAQ
Should I capitalize a family name after an initial (e.g., o'neill)?
Yes. Use the conventional capitalization: O'Neill, D'Angelo. When in doubt, check the person's own profile or official records.
Do I capitalize job titles after a name (e.g., John Doe, president)?
Usually no: John Doe, president of the company. Capitalize the title when it appears before the name (President John Doe) or in formal headings.
How should I handle brands that stylize in lowercase (like adidas)?
Use the brand's styling in marketing or quoted text. In formal or academic contexts, follow your style guide if it specifies otherwise; otherwise, using the brand's form is acceptable for accuracy.
Is it okay to lowercase names in casual texts and social media?
Casual contexts allow looser capitalization, but standard capitalization improves readability and avoids suggesting carelessness. If your audience intentionally lowercases everything, be consistent with that choice.
How can I quickly check many documents for lowercase names?
Use a grammar or style checker that flags proper-noun capitalization, then cross-check flagged items against official sources or a style guide for ambiguous cases.
