Missing hyphens in names (Harley Davidson, Miami Dade) are a common, easy-to-fix error. Below: the simplest rule, clear examples for work/school/casual writing, and ready-to-use rewrites you can copy.
Quick answer: Do these names need a hyphen?
Yes. Use the hyphen when the brand or place officially includes it: Harley-Davidson and Miami-Dade. Reproduce an entity's official spelling in formal or public writing.
- Match the organization's or place's official form: Harley-Davidson; Miami-Dade.
- Keep the hyphen with possessives: Harley-Davidson's announcement.
- If space is tight, prefer clarity-omit the hyphen only when it can't cause confusion.
Core explanation: why preserve hyphens in names
Hyphens join words into a single proper noun. Dropping the hyphen can split the name into two words, change how readers parse the phrase, or misidentify the entity.
- Hyphen = one lexical unit: Harley-Davidson, Miami-Dade.
- Using the official form respects brand identity and avoids ambiguity.
- In press, legal, or public-facing text, reproduce the exact spelling.
Hyphenation rules (quick, actionable)
Three simple rules:
- If the organization/place spells itself with a hyphen, copy that spelling.
- If two words act together as one proper noun, use a hyphen to show unity.
- Be consistent across a document or project.
- Wrong: I took my new Harley Davidson to the shop.
- Right: I took my new Harley-Davidson to the shop.
- Wrong: The Miami Dade mayor announced the plan.
- Right: The Miami-Dade mayor announced the plan.
Spacing, punctuation, possessives, and plurals
Keep the hyphen when you add punctuation or form possessives. For awkward plurals, either pluralize the base or rephrase.
- Possessive: Harley-Davidson's new catalog (hyphen stays, add 's).
- Plural: Harley-Davidsons (informal) or models from Harley-Davidson (cleaner).
- Punctuation: hyphens stay before commas, periods, and parentheses.
- Wrong: Harley Davidson's design team released a teaser.
- Right: Harley-Davidson's design team released a teaser.
- Wrong: We collected several Harley Davidson models for the exhibit.
- Right: We collected several Harley-Davidson models for the exhibit.
- Alternative (rephrase): We collected several models from Harley-Davidson for the exhibit.
