Proper Adjectives:
* What they are: Adjectives derived from proper nouns. They describe something that is specific or unique, related to a particular person, place, or thing.
* How they are formed: Often by adding "-an", "-ian", "-ese", or "-ish" to the proper noun.
* Examples:
* From People: Shakespearean (related to Shakespeare), Victorian (related to Queen Victoria)
* From Places: French (related to France), Canadian (related to Canada), Parisian (related to Paris)

* Function: Proper nouns are the subjects or objects of sentences. Proper adjectives modify (describe) nouns.
Examples:
