Today we’ll add a gleaming new ingredient to the adjective phrase: proper adjectives. Like a single, magical herb that tells you exactly where a potion ingredient comes from, proper adjectives name origin (geographic location), cultural background, or historical connection. Handle proper adjectives with care—capitalize them—so your grammar potion keeps its sparkle.

Proper adjectives can also express opinions related to these origins.

What are Proper Adjectives?

• Proper adjectives are adjectives formed from proper nouns. They tell the reader where something or someone originates, or they connect the noun to a notable individual, place (cities, countries, regions), culture, religions, brands, or historical period.
• Always capitalize proper adjectives because they come from proper nouns.
• Demonyms (also called gentilic forms) identify people by their place of origin: country, region, or city.

Examples

• The horrible, vicious, unknown monster devoured the small American girl.
• The brave Mexican explorer climbed the mountain.

How Proper Adjectives Are Formed

1. Direct Forms (no change)

• City or region names often stay the same:
  • New York → New York actors
  • Tokyo → Tokyo cuisine
• Brands and Institutions
  • Harvard → Harvard student
  • Sony → Sony headphones
• Religions and cultures
  • Christian → Christian music
  • Hindu → Hindu festival
  • Islamic → Islamic art

2. Suffix for Creating Proper Adjectives

• Nationalities and origins often take specific suffixes, such as: 
• -ian, -an, -ean, -ic, -ese, -ish, -i.
• Examples: Italian, Iranian, Greenlandic, British, Chinese, Spanish, Israeli

3. Unique Forms

• Some cities, states, or provinces have special adjective forms:
• Alaska → Alaskan
• France → French
• New York → New Yorker or New York
• Some countries have unique words for people from that place:
• The Netherlands → Dutch
• Greece → Greek

4. From People and Thinkers

• Proper adjectives can derive from individuals (often capitalized):
• Darwin → Darwinian
• Newton → Newtonian
• Shakespeare → Shakespearean

Hyphens and Prefixes

• Use a hyphen when attaching a prefix to a proper adjective.
• anti-Chinese
• pre-Shakespearean
• If the prefix itself includes a proper-name element, capitalize both parts:
• Austro-Hungarian
• Anglo-American
• Afro-Caribbean

Adjective Order

• Proper adjectives can be in the attributive position.
• When a proper adjective appears in a cumulative adjective sequence, follow the adjective order in Lesson 10.
• When proper adjectives are coordinate, separate with a comma, use “and,” or use both a comma and “and.” (Lesson 20 covers the rules.)
• They can also appear in predicate position with linking verbs.
• Example: The author is Irish.

Articles with Proper Adjectives

• Remember: articles “a,” “an,” and “the” modify the noun, not the adjective. When a proper noun is used adjectivally, article rules apply to the noun in the phrase.
• Example: The American wizard studies at Harvard.
• She is a French artist.
• This means that the article “the” or “a” specifies the noun “wizard” or “artist” while the proper adjective gives origin information.
