A proper noun or adjective in a hyphenated compound retains the capital:
- Greco-Roman
- trans-Canada
- neo-Nazi
- Pan-American
In general, do not capitalize prefixes or suffixes added to proper nouns:
- The President-elect will tour the mid-Atlantic States in an American-made car.
Titles of works
In titles of works, it was once customary to capitalize only the first element in a compound.
However, most style guides today recommend capitalizing all elements in such a compound except articles (a/an, the), coordinating conjunctions (and, but, for, nor, or, so, yet) and short prepositions of two or three letters:
- Half-Blood Blues
- English-Speaking Minorities in Quebec
- Use of Over-the-Counter Medications During Pregnancy
- Seizing That Once-in-a-Lifetime Opportunity
- Forty-Second Street
Headings
If headline-style capitalization is being used, follow the guidelines given above for titles of works.
However, if sentence-style capitalization is being used, do not capitalize the second or subsequent elements in the compound except in the case of a proper noun or adjective.
- Re-education for development
- Over-the-counter medications
- Non-French-speaking minorities
